Question

Find the perimeter and area of each of the squares whose sides are

$4.5m$

Answer 1

Sides of square $=4.5m$

Perimeter of square $=4\times side$

$$\begin{gathered} =4\times 4.5 \\ =18 \end{gathered}$$

So, the perimeter is $18m$

Area of square $=side\times side$

$$\begin{gathered} =4.5\times 4.5 \\ =20.25 \end{gathered}$$

Hence, the area of square is $20.25m^2$
