Let sides of the triangular plot be 2x, 3x and 4x.
Perimeter of a triangle = sum of length of all sides
900 = 2x+3x+4x
900 = 9x
900/9 = x ...(Transposing 9 to right side)
x = 100m
First side = 2x = 2×100 = 200m
Second side = 3x = 3×100 = 300m
Third side = 4x = 4×100 = 400m
Area of a triangle = √s(s-a)(s-b)(s-c)
Where a, b, and c are sides of the triangle and s is semi perimeter.
s= 900/2 = 450
Area of the triangle = √450×(450-200)(450-300)(450-400)
= √450 × 250 × 150 × 50
= 29,047.38
