Answer:
A = 126.6525 = 126.65 cm^2
Step-by-step explanation:
The formula for perimeter of a square is P = 4s, where s represents the sides of the square.
So, we have 45 = 4s and s = 11.25
The formula for area of a square is A = s^2, so we have A = 11.25^2 = 126.6525 = 126.65 cm^2
Round as much as you need.
