Question

The length of a rectangle is 5 inches more than the width. The perimeter is 46 inches. What are the length and the width of the rectangle?

Answer 1

`(l, w) = (14, 9)`

Explanation:

The perimeter is `p = 2l+2w`.

The first sentence tells us that `l = w + 5`, hence
`p = 2(w+5) + 2w = 4w + 10 = 46 implies w = 9`
Therefore, since `l=w+5`, `l = 14`.
