I have a perfect square the area is 36 what is the perimeter?

$24$ units

Explanation:

Let the side length of the square be $x$ units.

Then, as it is a perfect square, the area is ${x}^{2}$ sq. units
and it's perimeter is $4 x$ units.

${x}^{2} = 36$

$x = + 6 \mathmr{and} - 6 \left(r e j .\right)$

The square hence have a side length of 6cm.

Perimeter of the square

$= 4 \cdot 6$

$= 24$

Note 1: Area of a square equals to the width times the length, in which both are the same, giving ${x}^{2}$

Note 2: Perimeter refers to the sum of side lengths. As the square have 4 equal sides, the perimeter is $4 x$
