Question

1. the perimeter of a rectangle is 36 feet. if the length of one side is 10 feet, how wide is the rectangle?

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 $P = 36$ and $l=10$.

Step2: Substitute values into formula

$36=2(10 + w)$

Step3: Solve for $w$

First, divide both sides by 2: $\frac{36}{2}=10 + w$, so $18 = 10+w$. Then subtract 10 from both sides: $w=18 - 10$.

Answer:

8 feet
