Question

2. Each question carries $2$ marks.

(v) Find the area of a square whose perimeter is$16m$.

Answer 1

Finding the area of square.

The formula for the perimeter of the square$=4\times side$

According to the question,

Perimeter of Square $=16$

$$\begin{gathered} 4\times side=16m \\ side=\frac{16}{4}=4m \end{gathered}$$

Area of square$={\left(side\right)}^2={\left(4\right)}^2=16m^2$

Hence, The area of a square whose perimeter is$16m$ is $16m^2$
