At first, you have to divide the plot into a number of triangles.
Then you have to measure the distances of the sides of the triangles by calculating chains, or a tape. After that let the distance of the three sides be denoted by a, b, and c. after that area of each triangle can be calculated by the formula:
Area of triangle=s (s-a) (s-b) (s-c)
s= semi perimeter = a+b+c/2
Next, you have to take a summation of the areas of all the triangles calculated in the above step, and you will get the plot area.
Plot area = A1 + A2 + A3 +……..+ An
