Question

A Hall 10.5 m long and 8.5m wide is surrounded by a path of 3.5 m wide externally.find the area of the road and total part enclosed with road.

Answer 1

I just tried hope it will be right

Answer 2

The area of road is $182 m^2$

Step-by-step explanation:

Inner length = 10.5 m

Inner breadth = 8.5 m

Width of path = 3.5 m

Outer length = 10.5+(3.5+3.5)=17.5 m

Outer breadth = 8.5+(3.5+3.5)=15.5 m

Area of road = Outer area - inner area

Area of road =$(17.5 \times 15.5)-(10.5 \times 8.5)$

Area of road =$182 m^2$

Hence The area of road is $182 m^2$
