Question

rectangular plot of grass 40m by 25m has a gravel walk 1.5m

wide all around it on the out side. Find the area of the walk.​

Answer 1

Answer:

Length of grass plot = 25 m

Breadth of grass plot = 22 m

We are given that A rectangular plot of grass 25m by 22m has a gravel walk 1.5m wide all around it on the outside.

So, outer length = 40+(1.5+1.5)= 43m

Outer breadth =25+(1.5+1.5)=28m m

Area of Gravel walk = Outer area - Inner area

Area of gravel walk =(40 ×43 )-(25×28)

Area of gravel walk =1020m²
