Question

The cost of levelling a square lawn at Rs. 2.50 per square metre is Rs 17640.
Find the cost of fencing at Rs 5 per metre

Answer 1

Area = 17640/2.50 = 7056 square metre

As it is a square field

Area=side square

thus, side= underoot 7056=84m

perimeter =84x4 = 336 m

cost of fencing = 336*5=1680
