Question

A path 2.8 m wide runs along inside a square park of side 98 m. Find the cost of levelling the path at the rate of Rs 2.25 per m²

Answer 1

Area of path = area of ground including path - area of ground not including the path
=(103.6 ×103.6 )-(98×98)
=10732.96-9604
=1128.96

Cost of levelling = 1128.96×2.25
= Rs2540.16
