Question

A square lawn is surrounded by a path2 meters wide. If the area of the path is 120 sq.meters ,find the area of the lawn​

Answer 1

let the side of square lawn with path be x

Therefore,

The area of square =side×side

120=x sq

x= under root 120

x=2 under root 30

Therefore Now,

the side of square shape lawn = x-2

=2 under root 30 -2

= under root 30

Therefore Now,

The are of lawn= side × side

= under root 30 x under root 30

=30 sq.meter
