The Area of a rectangle is 3x2 + 9x square inches. The length of the rectangle is 3x inches. What is the width of the rectangle? 1. Explain how you find the area of a rectangle. 2. Explain how you find the width of a rectangle given the Area and the length. 3. Show you work and solve for the width of this rectangle.

x + 3

Step-by-step explanation:

1. The area of a rectangle is length times width.

A = LW

2. Solve for the width by dividing both sides of the equation by the length:

W = A / L

3, Plug in the expressions for A and L:

W = (3x² + 9x) / 3x

W = (3x² / 3x) + (9x / 3x)

W = x + 3

answer is c
