Question

8. A rectangular plot is 35 m long and 30 m broad. A road of uniform width of 2.5 m runs along the
boundary of the plot inside it. Find the cost of paving the road with bricks at 10 per sq. metre.​

Answer 1

Given

Length of the park = 50 m

Breadth of the park = 30 m

Area of the park = 50×30

=1500m

2

Width of the path inside the park = 2m

Length of the park without path = 50−(2+2)=50−4=46m

Breadth of the park without path = 30−(2+2)=30−4=26m

Area of the park without the path = 46×26

=1196m

2

Area of the path = Area of park - Area of park without path

=1500−1196

=304m
