A gardener is building a rectangular planter for vegetables. The length of the planter is 2 times its width and the total area is 24.5 square feet. What is the perimeter of the planter? Hint 1: Use the relationship between the length and width to write an area formula in one variable. The area formula is A=lw.

Hint 2: Solve the area equation to find the values of the width and length. Then find the perimeter using the formula P=2w+2l.
