Build up calculated field

so can you determine an area up a property on site hello my name is Cecil Han and you are watching an engineer boy actually there are many things I want to cover in this short video like in this video we will learn an area determination of simple geometric shapes and this will be little quick because everybody understand the basics so the main goal is to determine an area of irregular shapes like an illegal rectangle or in Hardware I can say in a regular polygons because everything is a polygon when it comes to an area determination except chef's having curves and the next thing I want explained is the misunderstanding of Engineers in common pathologies because I have seen many people especially on YouTube teaching in Irish bar Beulah's instead of correct formulas and the last thing which I want to discuss in this video is the mental calculation and then checking it with the help of Saphir to make sure at the calculation is ok or not so let's get started and I will start with an area of simple geometric shapes and it's actually so simple like in area of a square is its side square area of rectangle is the product of its two sides like length breadth multiplication area operating a triangle is one half of area of a rectangle or one half base times its height area of a scalene triangle can be calculated with the help of hiroba Mulla which i'm going to explain later LED area of an equilateral triangle can be found by the same parola as 1/2 times base times its height are zero point 4 3 3 times its side square area of a circle can be found with the help of PI R square R PI d square divided by 4 area of a regular polygon can be 1/2 x perpendicular times its parameter and so on I don't want to waste much time who are here because our main goal is to come every village heads so let's go ahead to talk about in every cooler shapes our properties remember whenever Lopez in a regular property on site and want to work out at Syria an easy way is to split the world property and the simple geometric shapes and the best thing according to me is the triangulation yes so you have to convert or split your property into triangles and then calculate an area of each triangle separately and add them together to get an area of the world property for example let's say if we have to determine an area of the given property so how can we do this stuff I'll just present I'll take a look to the boundary of the property and specify its corner with the help of renting rods are in arrows you can also use P support and sticks if you work and do not have rods pegs are in arrows appear specifying all corners then measure all the edges of the property once you are done with the edges then just take measurements are the diagonals to have triangles of course and here I'm going to repeat that diagonal is must or hair in the same situation if you do not take diagonal you cannot calculate the correct area of the property you can only calculate an average video which is not actually the solution of the problem once you take our measurements then level each triangle with numbers like in my situation let's say triangle one and triangle two and then do your manual calculation and let's do just a Manilla calculation who are here remember in this calculation I'm going to calculate an area of the property with the help of two per Mulas and we will compare the answer of each per mullah with the answer of software to check and satisfy which pamela is okay and which one per mullah does not give the correct answer so let me call one solution with the wrong solution and one with the correct solution and I will start from the wrong solution which is bothered by most people and students for example this one method in para mula let's talk about this one according to this formula take an average of the opposite sides and multiply it with in orig of the other two sides to get the wall area of the given shape like in this case the total area of the property must be sixty three point two pipe + 58 divided by two which is the average of two opposite sides times 77 + 55 divided by two which is the average of the other remaining sides and that's actually not the correct answer right but however we are doing your hair just to satisfy the solution I let a lay it right and if you do little math with the given formula of course we can get the total area equals 4,000 and 1.2 pipes were peeled and now let's come into the correct calculation which I want you to do on the Sun side and I'm sure this will take enough time but I'm also sure this calculation is the correct calculation the best way over here is to use the hero / moon upper each triangle and let me determine an area of the triangle 1 and triangle past all sides are known so I can calculate the seamy perimeter of the triangle like s equal summation of all sides divided by 2 or you can say s equals 55 plus 63 point 2 pi plus 75 and divided by to do little math with this of course we can get the seamy parameter at the triangle equals ninety six point six two pi appeared and now let's put all the videos in the hero parabola so area equals square root S which is ninety six point six two five times again is minus one side which is 55 into s gain - other side which is of course 63 0.25 times s and - the last sign which is 75 feet at lose your mind at your calculator of course you can end up or you should end up with an area equals one thousand seven hundred and three point seven six eight square feet is the area of triangle first now let's calculate an area of the second triangle and of course we'll do the same thing as we did for the area of the past triangle so when you do calculation per an area of the second triangle you should end up with an area equals 2036 point zero two six square field and finally let's add in area of the board triangle to have the total area of the property so the total area must be in area of the triangle first plus in area of the second triangle our total area equals one thousand seven hundred and three point seven six eight plus two thousand and twenty six point zero two six which is of course the total area equals three thousand seven hundred and thirty nine point seven nine four square field now let's draw the same property in our to gate to check which one Pamela is okay and I will draw this little quickly because I don't want to waste how much time and I don't want the video to be longer so let's write little quickly so as you can see I have drawn the same property which area was determind by me a few seconds ago now let me fly a nice function up in art okay to determine its area per which we will type and enter double a in command bar after which will type and enter open an object and then we'll simply click in object at the boundary of our property AutoCAD will show the total area of the property in the command bar you can of course copy and and where you want so according to the software gets the article the total area of the plot our property is three thousand seven hundred and thirty nine point seven nine port square peeled and now let's decide which one formula or which one method is okay of course the last method I mean an area by hero Pamela is okay so next time please do not use this hard upon Muna's because the difference is a very huge so whenever you want to calculate area of an irregular shape the best thing is to split the world property into triangles and then calculate area of each triangle after death you can add them together of course to get the world property area and that's it and the last thing I want to do is asking a question from you I want you to calculate an area of a triangle which does help all sides as shown I'm sure also of course that you cannot solve it so I want to solve it as well remember this geometry does not have any area because this is not a triangle you can ask me how because some of two sides of the triangle must be greater than the third one and the shown triangle does not satisfy the rule so this is not a triangle which means the whole thing does not have any area and they're set and now come on I want a like share and
