Question

A rectangular ground is 120 metre long and 90 metre broad. In the middle of the ground, there is a circular tank of radius 28 metre. Find the cost of turfing the remaining portion at the rate of ₹
15 per square metre

Answer 1

Area of ground= (120×90) m^2

= 10800m^2

Area of the circular tank= 22/7×28×28

= 2464m^2

Remaining area = (10800-2464) m^2

= 8336m^2

Cost of turfing = Rs. (8336×15)

= Rs. 125040
