To solve this problem, it is helpful to start by creating an equation. For this equation, the width will be represented as x. We know that the length is twice as much as the width, which means the length is 2x. There are 2 width sides and 2 length sides, so our equation is x+x+2x+2x = 135, or 6x = 135. To find the value of x (which I understand you don't have to do, however this is helpful for future reference) divide 135 by 6. You will get 22.5. This means x, the width is 22.5 feet, and the length, which is 2x is 45 feet. I hope this helped! Could I possibly get brainliest?
