Question

The length of a rectangle is 12 inches more than its width. What is the width of the rectangle if the perimeter is 42 inches?

Answer 1

Let the width be `x` and the length be `x + 12`.

Then,

`x + x + 12 +x +x + 12 = 42`

`4x + 24 = 42`

`4x = 18`

`x = 9/2`

The width is `9/2` inches.

Hopefully this helps!
