Question

example 8: find the length of a rectangle with a perimeter of 30 yards and width of 6 yards.

Explanation:

Step1: Recall perimeter formula

$P = 2(l + w)$ (where $P$ is perimeter, $l$ is length, $w$ is width)

Step2: Substitute given values

$30=2(l + 6)$

Step3: Solve for $l$

$15=l + 6$, then $l=9$

Answer:

9 yards
