Refer to the above figure, which shows a square garden (in green) surrounded by a dirt path (in orange). The dirt path is seven feet wide throughout. Which of the following polynomials gives the perimeter of the garden in feet?
The sidelength of the garden, in feet, is 2×7=14 feet less than that of the entire lot, or
