You can put this solution on YOUR website! Start with the formula for the perimeter of a rectangle: where L = Length and W = Width.
The problem states that "It is twice as long as it is wide", so... Substitute into the formula: and P = 90 m, so... Divide both sides by 2. Divide both sides by 3. so... m. and m.
