Question

If the perimeter of a square is 16 cm, then its area is:

• A. $4c{m}^2$
• B. $8c{m}^2$
• C. $16c{m}^2$
• D. $32c{m}^2$

Answer 1

The correct option is C

$16c{m}^2$

Given: Perimeter = 16 cm
Perimter of a square = 4 $\times$ Side
$\Rightarrow$ 16 cm = 4 $\times$ Side
$\Rightarrow$ Side $=\frac{16}{4}=4cm$

Area of a square = Side $\times$ Side
$\Rightarrow$ Area of the square $=4cm\times 4cm=16c{m}^2$
