The clayton family’s pool has vertices at the coordinates (0, 2), (0, 5), (2, 5), (2, 6), (5, 6), (5, 1), (2, 1), and (2, 2). if each grid square has an area of 9 square feet, what is the area of the pool?

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top

2f(x)= x+3 if 4 < x < 8 2x if x 28 2
