How To Calculate Land Area Or Plot Area:
Sometimes we may need to know the area of any land or plot for various reasons, such as buying, selling land, or constructing house/building, etc. In this article, I will explain how to calculate land area or plot area for a site.
Area Formula For Different Shapes is given below:
But for complex-shaped land, you cannot easily calculate the area. In that case, we use HERON’s Formula, which is given below:
Land Area Calculation:
Where S = Half of the Perimeter of the triangle
S = (a + b + c)/2
a = Distance of AB
b = Distance of BC
c = Distance of AC
Let’s take an example,
First of all, divide the land area into minimum possible no. of triangle. Then measure all the required distance (like AB, AC, AE etc) by using a tape or chain.
1. For △ ACD:
AC = 10 feet.
CD = 12 feet.
AD = 14 feet.
S = (a + b + c)/2 = (10 + 12 + 14)/2 = 18 feet.
2. For △AED:
AD = 14 feet.
AE = 14feet.
DE = 12 feet.
S = (a + b + c)/2 = (14+14+12)/2 = 20 feet.
3. For △AEB:
AB = 16 feet.
BE = 12 feet.
AE = 12 feet.
S = (a + b + c)/2 = (16 + 12 + 12)/2 = 20 feet.
Total Area Of Land = 58.78 + 75.89 + 71.55 = 206.22 ft²
Note:
This method does not give appropriate results for curve shaped areas, for curve shaped areas, we need to use definite integral method.
I hope you now have enough knowledge about plot area calculation. If you have any problem or question, you can ask in the comments.
