Question

The perimeter of your closet is equal to 18 feet. The difference of the length and width equals one foot. What are the dimensions of your closet?

Answer 1

`4'` x `5'`

Explanation:

If the length is `x` and the width is `y`, then the perimeter `p = 2x+2y`

In addition, `x=y+1`
`:. 2(y+1)+2y = 18`
`4y = 16`
`y=4`

`:.x=5`
