Question

If the perimeter and area of a square are numerically equal, then find the side of the square.

• A. $1$ unit
• B. $6$ units
• C. $2$ units
• D. $4$ units

Answer 1

The correct option is D $4$ units

Given:
Magnitude of the area of the square = Magnitude of the perimeter of the square
Let the side of the square be '$a$'.
We know that area of the square is $a^2$ and the perimeter is $4a$.
Now,
$a\times a=4\times a$
$\Rightarrow a=4units$
Hence, the side of the square is $4$ units.
