- A garden is 6 meters longer than it is wide. The garden's
- area is 16 square meters. What are its dimensions?

- Let w be the width. Then the length is (w + 6).
- The area is w*(w+6), so the equation to solve is
- w*(w+10) = 16, or w^2 - 6*w - 16 = 0.

- The width of the garden is 2 meters and the
- length (w+6) is 8 meters. (Why is the root of -8
- not a solution to the problem?)
