Jennifer plans to fence a rectangular area around her rectangular swimming pool. The total area enclosed by the fence, including the pool, should be 5 times the area of the pool alone. The pool is 20 feet by 17 feet. What is the total area enclosed by the fence?

5 * 20 * 17 = _____ sq. ft.

since the area enclosed by the fence is 5 times the area of the pool, and we know that the pool is 20*17= 340 sq ft, we can multiply 340 * 5 to get ____

1700 sq. ft.
