Maria is buying new carpet. her bedroom is in the shape of a square and the length id each side is 12 feet. write and simplify an exponential expression to find how much carpet she needs.

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 =

So , the area of the bedroom =  [which is an exponential expression]

Simplify it

The area of the bedroom =

Also, the carpet she needed = Area of the bedroom.

Thus , She needed 144 square feet of carpet.
