We are given a pool shaped like a right triangle where the two legs are measured 41 ft and 40 ft. We are asked for the perimeter of the pool. To answer this, we determine first the hypotenuse of the triangle. The hypotenuse is equal to

. Hypotenuse is equal to 57.28 ft. The perimeter is equal to 41 + 40 + 57.28 ft, 138.28 ft.
