Question

The perimeter of a square is $24$ units. What is its area?

• A. $36$ square units
• B. $30$ square units

Answer 1

The correct option is A $36$ square units


The perimeter of a square will be sum of all its $4$ sides. Here the perimeter is $24$ units. If the side of the square is $s$, then,
$s+s+s+s=24$
or, $4$ times $s$ is 24
$=4s=24$
$=\frac{4s}{4}=\frac{24}{4}$
$=s=6$ units

So, the side of this square is $6$ cm
Area of a square $=s\times s$
Therefore, the area of the square will be $=6\times 6=36$ square unit.
