A small backyard measures 45 feet on one side. The other side measures (h 20) feet. How many feet around is the yard?

The yard is 130 feet around.

Explanation:

Assuming the small backyard is a rectangle than you can determine how far around the yard is by using the formula for the perimeter of a rectangle which is $p = \left(2 \times l\right) + \left(2 \times w\right)$ Where $p$ is the perimeter, $l$ is the length, and $w$ is the width.

In this problem we are given the length or $l$ as 45 feet. We are also given the width or $w$ as 20 feet. Substituting these into the formula and then solving gives:

$p = \left(2 \times 45 f e e t\right) + \left(2 \times 20 f e e t\right)$

$p = \left(90 f e e t\right) + \left(40 f e e t\right)$

$p = 130 f e e t$
