If the sides of a triangular field measures 52m, 37 m and 20 m, then the cost of leveling at Rs 5 per m^{2} is Rs 1530.

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 m^{2}

It is given that,

Cost of leveling 1 m^{2} area = Rs 5

∴ Cost of leveling 306 m^{2} area = 5 × 306

= Rs 1530

Hence, the given statement is true
