A rectangle is twice as long as it is wide. it's area is 72 square units. Find the length of each side

The length of the rectangle is 6 and the width is 12.

Step-by-step explanation:

We start by listing the length as x and the width as 2x. Now we can find the value of each side by multiplying the together and setting it equal to 72.

2x * x = 72

2x^2 = 72

x^2 = 36

x = 6

Now we have the length. We can find the width by plugging it into the equation.

2x = width

2 (6) = width

12 = width

Length is 12 square units and width is 6 square units. Area is length times width. So find out the factors of 72.
