Hillary is looking to purchase a piece of land to build a library.The rectangular plot of land has a length (∫) that is 25 feet longer than its width (w). The total area of the land is 6600 square feet. Which of the following best models the scenario?

• ∫ + w = 6600

• ∫ ⋅ (∫ + 25) = 6600

• 2 ⋅ (w + 25) = 6600

• w ⋅ (w + 25) = 6600
