Question

1. the perimeter of a rectangle is 50 feet. the length of one side is 13 feet. what is the width of the other side?

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. Given $P=50$ and $l = 13$.

Step2: Substitute values into formula

$50=2(13 + w)$

Step3: Solve for $w$

First, divide both sides by 2: $\frac{50}{2}=13 + w$, so $25=13 + w$. Then subtract 13 from both sides: $w=25 - 13$.

Answer:

12 feet
