Janet has a rectangular shaped pool measuring 20 ft. by 15 ft. with a uniform 3 ft. sidewalk surrounding the pool. At one of the 15 ft. ends, she has a semi-circular flower garden, also surrounded by a 3 ft. sidewalk. She will put a 3 ft. wide gate along the perimeter. How much fencing material will Janet need to completely enclose the outside of the perimeter of the pool and garden area?
