Answer:

8 units

Step-by-step explanation:

<u>Area of a rectangle</u> = <em>Width</em> multiplied by Length

Substitute in all the known numbers into this formula to get

<u>72</u> = <em>(9)</em> × (2x+4)

Solve the equation for x, to find out the length

9(2x+4)=72

2x+4=72/9

2x+4=8

2x=8-4

2x=4

x=4/2

x=2

Length of the rectangle = (2x+4)

2(2)+4

4+4=8
