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

189 square feet.

Step-by-step explanation:

If we draw these coordinates in the X-Y coordinate plane, we can see the area enclosed by the vertices, count how many grid squares we have, and then multiply the number of squares by the area of 9 square feet.

Seeing the image attached, we can count 21 grid squares inside the figure made with the vertices (to form the sides of the pool, we connected each subsequent vertix).

So the area of the pool is 21 * 9 = 189 square feet.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
