Q. 5.     A path $1\; m$ wide is built along the border and inside a square garden of side $30\; m$. Find:            (i) the area of the path.

R Riya

Is is given that side of square garden is $30\; m$

We know that area of square is = $a^2$

$\Rightarrow a^2 =(30)^2 =900 \ m^2$                   -(i)

Now, area of square garden without 1 m boarder is

$\Rightarrow a^2 =(28)^2 =784 \ m^2$                              -(ii)

Area of path is (i) - (ii)

$\Rightarrow 900-784 = 116 \ m^2$

Therefore,  area of path is  $116 \ m^2$
