Answer:
a
Step-by-step explanation:
the perimeter (P) of a square is the sum of the 4 congruent sides.
the area of a square is calculated as
area = s² ( s is the length of a side )
here area is 36 , then
s² = 36 ( take square root of both sides )
s = [tex]\sqrt{36}[/tex] = 6
then
P = 4s = 4 × 6 = 24 cm
