Question

The perimeter of a square is $16\text{cm}$. What is its area?

• A. $18\text{sq.cm}$
• B. $24\text{sq.cm}$
• C. $16\text{sq.cm}$
• D. $14\text{sq.cm}$

Answer 1

The correct option is C $16\text{sq.cm}$

Perimeter of a square $=4\times$ length of side
$⟹4\times s=16\text{cm}$
$⟹s=4\text{cm}$

Area of a square $=s\times s$
$=4\text{cm}\times 4\text{cm}$
$=16\text{sq.cm}$
