How to Calculate Land Area at Site

This is another useful presentation from L & T - Learning Technology. In this construction video, he will teach you how to calculate land area at site.

The Solution is Heron’s Formula: If there is a triangle having three sides (a, b and c), and if you know the measurement of the three sides, then

Area=

Where s is semi perimeter

And s = (a + b + c)/2

Let’s suppose there is a land having irregular shape and we need to find the area of the land.

In triangle ABD

AB (a) = 3 m

BD (b) = 4 m

AD (c) = 5 m

S = a + b + c /2 = (3 + 4 + 5)/2 = 6 m

Area=

In triangle BCD

BC (a) = 3 m

CD (b) = 3 m

DB (c) = 4 m

S = (3 + 3 + 4)/2 = 5 m

Area = 4.47 m²

In triangle ADE 

Area = 3.8 m2

Total area = 6 + 4.47 + 3.8 = 14.27 m²
