B. A (w) = w∧2+4w

Step-by-step explanation:

Let the width of the rectangle be w.

The length is 4 feet longer than the width = w+4

Area of a rectangle = length * width

A=L*W

= (w+4) * w

Opening the brackets gives the:

A=w²+4w

Therefore the expression for the area in terms of width is A (w) = w∧2+4w
