A rectangle has an area of 72 square units. The width of the rectangle is 9 units. The length of the rectangle is 2x + 4.

What is the rectangle's length?

Answer 1

[AI-generated answer — Bot]

We know that the area of a rectangle is equal to its length multiplied by its width: A = lw. We also know that the width is 9 units. So we can plug in these values and solve for the length:

A = lw
72 = 9(2x + 4)
72 = 18x + 36
36 = 18x
x = 2

Therefore, the length of the rectangle is:

l = 2x + 4
l = 2(2) + 4
l = 8

So the rectangle's length is 8 units.
