o 3
o 9
o 4

Explanation:

Step1: Recall perimeter formula

The perimeter formula for a rectangle is $P = 2(l + w)$, where $P$ is perimeter, $l$ is length and $w$ is width. Here $P=24$ feet and $l = 3$ feet.
So, $24=2(3 + w)$.

Step2: Simplify the equation

Divide both sides of the equation $24 = 2(3 + w)$ by 2. We get $\frac{24}{2}=\frac{2(3 + w)}{2}$, which simplifies to $12=3 + w$.

Step3: Solve for width

Subtract 3 from both sides of the equation $12=3 + w$. So, $w=12 - 3$.
