Arectangle's length is 4 feet more than its width. write a quadratic function
that expresses the rectangle's area in terms of its width.
a. a(w) = w^2 – 4w
b. a(w)= w^2+4w
c. a(w)=w+4
d. a(w) = lw

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

won't that be plagrisim thought?
