Lee just bought a house with open land in the backyard to create a rectangular garden.
He has 46 linear feet of fencing and wants to create a garden with the largest possible
area to plan vegetables and herbs. If he makes the length of the garden 13 feet, the
garden will have an area of 130 square feet. If he makes the length of the garden 11.5
feet, the garden will have a maximum area of 132.25 feet. The area of the garden, A, in
square feet, is a function of the length, x, in linear feet.
