Question

The length of a rectangle is 3 more than twice its width. If the perimeter of the rectangle can be no more than 78 ft, what are all of the possible widths of the rectangle?

Answer 1

Width is `12` feet.

Explanation:

Let the width be `w`, then length would be `3+2w` and perimeter would be

`2xx(w+3+2w)=2xx(3+3w)=6+6w` and

`6+6w=78`

or `6w=78-6=72`

and `w=72/6=12`

Hence, width is `12` feet
