A garden 120 m long & 75 m wide has a road of 4m wide all along the outside. Find the cost of levelling the road at Rs. 7 per sq.m.
Answers
Step-by-step explanation:
Area of the garden with the road= 120m × 75m
= 9,000 sq.m.
Length of the garden without = 120m - 4m × 2
the road = 120m - 8m
= 112m
Breadth of the garden without = 75m - 4m × 2
the road = 75m - 8m
= 67m
Area of the garden without the = 112m × 67m
road = 7504 sq.m
Area of the road = Area of the
garden with the
road - Area of
the garden
without theroad
=9000sq.m-7504
=1496sq.m
Cost of levelling the road per. =Rs 7
sq.m
Total cost of levelling the road. = 1496sq.m × Rs 7
= Rs 10472
