A rectangle is twice as long as it is wide. Its area is 128 square
meters. What are the dimensions of the rectangle?

Hello Kirsten,

Let 'w' be the width of the rectangle.
If its length is twice its width then its length is 2w.
We are given that the area of the rectangle is 128 square meters.
What is the formula for the area of a rectangle?
After you have that, you can solve for 'w'.
