A pool 100 yards by 150 yards with an area of 15,000 square yards, fenced with 25 yards by 50 yards with an area of 1,250 square yards.What is the perimeter?

Question

The local community decides to install a pool beside the park.  The pool area will be a rectangular region of 100 yards by 150 yards with an area of 15,000 square yards.  The pool itself will take up an area of 25 yards by 50 yards with an area of 1,250 square yards.  The community will put up a fence so that only paying members can enter.  What is the perimeter of the pool area, in yards, that the fence will cover?

Answer 1

Since the pool area is what you're looking for - you want to find the perimeter of the entire area (and don't necessarily need the info about the pool itself).  The pool area is a rectangular region of 100 yards x 150 yards.  We need the perimeter of that, which is 2(100) + 2(150) = 200 + 300 = 500 yards.
