Question

A path $1m$ wide is built along the border and inside a square garden of side $30m$ . Find
the area of the garden

Answer 1

Since the path is built inside a square garden

A new square is formed after the path is built

Width of path is $1m$

So side of new square will be $30-1=29m$

Area of the path is ${29}^2=841m^2$
