Question

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

Answer 1

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 = (2 xx l) + (2 xx w)` 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 = (2 xx 45 feet) + (2 xx 20 feet)`

`p = (90 feet) + (40 feet)`

`p = 130 feet`
