Question

The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 fett, what is its length?

Answer 1

13 feet

Explanation:

If the length is 3 less than 2x the width, you can set up the equation 2(2w-3) + 2(w) = 72 and solve. That gives you w = 8. Lastly plug it in and that gives you 13.
