Question

The sides of a triangular ground are 5mt, 7mt and 8mt respectively. Find the cost of levelling the ground at the rate of Rs10. Per m. square

Answer 1

Assume that the height, base and the hypothesis of the triangular ground is 5mt, 7mt and 8mt respectively:

Area of the triangular ground
= (5*7/2) m^2
=35/2m^2
=17.5m^2

Cost of the levelling ground
= Rs(17.5*10)
= Rs 175

The levelling ground costs 175Rs.
