Question

If the perimeter of a square is 24 units, then its area is:

• A. $18$ sq. units
• B. $27$ sq. units
• C. $36$ sq. units
• D. $45$ sq. units

Answer 1

The correct option is C $36$ sq. units

Let the length of the side of the square be $s$.
Since, we know perimeter of a square
$=4\times$ side
$\Rightarrow 24=4s$
$\Rightarrow s=6$ units
Also, we know area of a square $={\text{side}}^2$
$\therefore$ area $=s^2=6^2=36$ sq. units
