How to calculate plot area?

The calculation of plot area is important for government authorities as well as the owners of the land. The government needs this data as a part of land survey whereas the owners need to know this information to determine the exact land area they have and finally utilize it in the best way possible. Anyway, the process is not that simple and a lot of math and formulas go into it. I am going to share with you the ways on how to calculate plot area here so bear with me. How to measure plot area? If only plots were cut according to the usual geometrical shapes, it would have been really convenient to put the formula and values in place and calculate the plot area. But this is not so. The plots are usually found in the following shapes:

• Square or rectangular plots
• Irregular polygon plots
• Triangular plots

If you are lucky enough to have a square or rectangular plot, then the calculations will be really simple. Here is how that could be done: Square plot Area = (length x length)  So the calculation will be: suppose the length of the plot is 30 feet then the area will Area of a square plot = (30 x 30) Area of a square plot = 900 feet   Rectangular plot area = length x breadth Suppose the length of your plot is 30 feet and breadth is 20 feet then the area will be: Area of rectangular plot = Length x Breadth Area of rectangular plot = 30 x 20 Area of rectangular plot = 600 feet   Triangular plot area = Area = √(s(s-a)(s-b)(s-c)) Here s is half the perimeter of the triangle, and a, b,c are sides Suppose a plot has three sides measuring the length of 14m, 24m and 18m respectively. Here is how you will calculate the area of a triangular plot. Area of triangular plot = √(s(s-a)(s-b)(s-c)) S = (a+b+c)/2 S = (14+24+18)/2 s= 28 Area of triangular plot = √(28(28-14)(28-24)(28-18)) = √(28(14)(4)(10)) = √(28(14)(4)(10)) = √15680 = 125.2 m, i.e., 1347.6 feet Area of irregular polygon plot If your plot has an irregular polygon shape then you will have to draw a map of it and divide the area in legible shapes and calculate the area of each polygon. Once you have all the values, just add them up. I hope now we are clear about how to calculate plot area.
