a rectangular field measuring 75m by 70m has some 2.5m wide path running around outside it...find the cost of gravelling this path at the rate of rupees 9 per sq.m
Answers
Answer:
Length of the rectangular lawn=75m
Breadth of the lawn=60m
Width of the road=4m
Area of the road(ABCD) parallel to the length of the lawn = 75m×4m
=300m
2
Area of the road(EFGH) parallel to the breadth of the lawn = 60m×4m
=240m
2
Area of the common area in both ABCD and EFGH = 4m×4m
=16m
2
Total area of both the rectangular roads = 300+240−16
=524m
2
Cost of gravelling the roads per m
2
= Rs.4.50
Cost of gravelling the roads for 524m
2
=4.50×524
=2358
Cost of gravelling the road is Rs.2358
