If the sides of a triangular field measures 52m, 37 m and 20 m, then the cost of leveling at Rs 5 per m2 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 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
