Answer: She needed 144 square feet of carpet.
Step-by-step explanation:
Given : Maria is buying new carpet. Her bedroom is in the shape of a square.
The length of each side is 12 feet.
We know that the area of square = [tex](side)^2[/tex]
So , the area of the bedroom = [tex](12)^2[/tex] [which is an exponential expression]
Simplify it
The area of the bedroom = [tex]12\times12=144\ \text{ft}^2[/tex]
Also, the carpet she needed = Area of the bedroom.
Thus , She needed 144 square feet of carpet.
