Question

lauras new bedroom is in the shape of a square and has an area of $144\\ \mathrm{ft}^2$. what should laura do to find the length of each side of her bedroom? \\(\bigcirc\\) a. divide the area by 2. \\(\bigcirc\\) b. divide the area by 4. \\(\bigcirc\\) c. take the square of the area. \\(\bigcirc\\) d. take the square root of the area.

Explanation:

Step1: Recall square area formula

The area $A$ of a square is $A = s^2$, where $s$ is the side length.

Step2: Solve for side length

Rearrange the formula to isolate $s$: $s = \sqrt{A}$

Step3: Match to the options

This means we take the square root of the area to find $s$.

Answer:

D. Take the square root of the area.
