## 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 of 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 are 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.

S = (a + b + c)/2 = (10 + 12 + 14)/2 = 18 feet.

2. For △AED:

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 result for curve shaped area, for curve shaped area we need to use difinite integral method.

I hope you have now enough knowledge about plot area calculation. If you have any problem or question you can ask in the comments.

1. I need more details about calculating land area

• Please correct the below point.

S = Semi-Perimeter of the Triangle.

Semi-Perimeter is half of its Perimeter.

2. Please explain it more to me ,I don’t understand it .it is principal scope of our field.
