Assuming the walkway is completely around the pool and within the fence, largest pool diameter is d-24.
George has enough fencing to enclose 2400 square feet around a circular pool. If he builds a circular fence and he wants 12 foot walkway around the pool, what is the largest pool diameter possible?
