Question

1. the perimeter of a rectangle is 60 feet. if the length of one side is 12 feet, what is the length 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 $P = 60$ and assume $l=12$.

Step2: Substitute values into formula

$60=2(12 + w)$

Step3: Solve for $w$

First, divide both sides by 2: $\frac{60}{2}=12 + w$, so $30 = 12+w$. Then subtract 12 from both sides: $w=30 - 12$.

Answer:

18 feet
