Step-by-step explanation:

The answer is B solely because they are both the same number, just on different sides of the zero.

The formula for the area of a square is:

A=s2

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 cm2=s2

We can take the square root of each side of the equation giving:

√225 cm2=√s2

15 cm=s

s=15 cm

The formula for the perimeter of a square is:

p=4s

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=4×15 cm
