Question

A rectangular grassy plot is $112m$ long and $78m$ broad. It has a travel path $2.5m$ wide all around it on the sides. Find the area of the path.

Answer 1

Length of rectangular grassy plot $=112m$ long and
Breadth $=78m$
Therefore, the outside area of rectangular grassy plot $=L\times B=112\times 78=8736m^2$
Total Area of Plot $=8736m^2$
It has a gravel path $2.5m$ wide all around it on the inside.
Then, Grassy area $=(112-5)(78-5)=7811m^2$
Area of Path $=$ Area of total plot $-$ area of inside (grassy area)
$=8736-7811=925m^2$
