Question

You install 542 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 123 feet. What is the length of the yard?

Answer 1

148 feet

Explanation:

Perimeter = Length + Length + Width + Width

542 feet = Length + Length + 123 feet + 123 feet

2 Lengths = 542 feet - 123 feet - 123 feet = 296

1 Length =
`296\ feet/2=148\ feet`

The length of the yard is 148 feet.
