Answer:

#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 #4x# units.

#x^2=36#

#x=+6 or -6 (rej.)#

The square hence have a side length of 6cm.

Perimeter of the square

#=4*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 #4x#
