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
