A rectangular lawn, 74 m by 60 m, has two roads, each road 4 m wide, running through the middle of the lawn, one parallel to length and the other parallel to breadth, as shown in the figure. Find the cost of gravelling the roads at Rs. 50 per `m^(2)`.

Text Solution

Verified by Experts

The correct Answer is:
Rs. 26200
Area of roads = area ABCD + area PQRS - area EFGH
`=(75 xx 4)m^(2)+(60 xx 4)m^(2)-(4 xx 4)m^(2) = (300 + 240 - 16)m^(2) = 524 m^(2)`.
