# If the sides of a

Answer :

Let the sides of the triangular field be:

a = 52 m, b = 37 m and c = 20 m

s = = = = 54 m

Now, by using Heron’s formula we get:

Area of triangle = = = = = 17 × 2 × 3 × 3

= 306 m2

It is given that,

Cost of leveling 1 m2 area = Rs 5

Cost of leveling 306 m2 area = 5 × 306

= Rs 1530

Hence, the given statement is true
