- A rectangular garden has a length 5 meters more than twice its width. If the area is 150 square meters, find the dimensions.
- Let width be \( w \). Then length is \( 2w + 5 \).
- \( 2w^2 + 5w - 150 = 0 \).
- Using the quadratic formula, \( w = \frac{-5 \pm \sqrt{25 + 1200}}{4} \).
- \( w = \frac{-5 \pm 35}{4} \).
