Answer and Step-by-step explanation:
First, we need to find out the circumference of the circle.
We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.
2
r
<u>Plug in 1 for r.</u>
=
= circumference of circle
<u>Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.</u>
<u />
x 4 =
= perimeter of square
<u>Now, divide the perimeter by 4 to get what the side of the square is.</u>
<u />
÷ 4 = 
<u>Now, multiply </u>
<u> by </u>
<u> (side times side) to get the area.</u>
x
= 
The answer is A.

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 = 
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.
