Select the correct answer. The length, l, of a rectangle is modeled by the equation l = w + 4, where w is the width of the rectangle in centimeters.

Two equations have been determined that represent the area of the rectangle, A, in square centimeters:

The first equation was created using the formula for the area of a rectangle: A = w2 + 4w.
The second equation models the relationship between the rectangle's area and width: A = 4w + 45.
