For this, we can say that x is equal to the width. Since the length is twice it's width, we can say that 2x is equal to the length. We know that the formula to get the area is , so that means that in other words . Let's divide both sides by 2 . let's find the square root of both sides . So . Since the width is 3 that means the length is 6 because the length is twice the width. The length is 6 inches and the width is 3 inches. I hope I helped you!
