Step-by-step explanation:
The formula for the area of a square is:
A
=
s
2
Where:
A
is the area of the square.
s
is the length of the side of a square.
Substituting and solving for
s
gives:
225
cm
2
=
s
2
We can take the square root of each side of the equation giving:
√
225
cm
2
=
√
s

15
cm
=
s
s
=
15
cm
The formula for the perimeter of a square is:
p
=
4
s
Where:
p
is the perimeter of the square.
s
is the length of the side of a square.
Substituting for
s
from the solution for the previous formula and calculating
p
gives:
p
=
4
