Question

A rectangular lawn is $15m$ long and $9m$ wide. It has a path $1.5m$ wide around it. Find the area of the path.

Answer 1

Given length of rectangular lawn is $15m$

Width of rectangular lawn is $9m$

Width of lawn without path is $9-1.5=7.5m$

Area of the lawn is $15\times 9=135m^2$

Area of the lawn without path is $15\times 7.5=112.5m^2$

Area of the path is $135-112.5=22.5m^2$
