Question 555016
Length = l
Width = w
The length of a rectangle is 3 inches greater than the width = l = w+3
Area of rectangle = a



A. Write a polynomial that represents the area of the rectangle.
a=lw
a=w(w+3)
a=w^2+3w
w^2+3w-a=0




(B)
Find the area of the rectangle when the width is 4 inches
a=w^2+3w
w=4
a=(4)^2+3(4)
a=16+12
a=28 sq inches
