Question

Rachel was carpeting a square-shaped room. The area of the room was 228 square feet. Which of the answer choices shows the length of the room to the nearest whole number

Answer 1

Since the area has a square -shaped we can conclude that the area is given by:

`A=l^2`

Where:

l = Length of the side

For A = 228:

`228=l^2`

Solve for l:

`\begin{gathered} l=√(228)m \\ l=2√(57)m \\ l\approx15.1m \end{gathered}`
