A construction company is planning to pour concrete for a driveway.
The length of the driveway is 16 feet longer than its width "w".
Length is "w+16".
-----------------------------
32. Write an expression for the area of the driveway.
Area = w(w+16) = w^2+16w sq. ft.
------------------------------------------
33. Find the dimensions of the driveway if it has an area of 260 square feet.
Solve 260 = w^2+16w
w^2+16w-260 = 0
(w+26)(w-10) = 0
Positive solution:
width = 10 ft
length = 10+16 = 26 ft.
