Celia is designing a pool for her backyard. It is in the shape of a rectangle, and on her design 1 unit=1 ft. On her graphed design, the corners of the pool are at (28,12) , (18,12) , (18,4) , and (28,4) . What is the area of her pool?(1 point)
To find the area of the pool, we need to find the length and width of the rectangle formed by the corners given.
The length of the rectangle is the distance between the points (28,12) and (18,12), which is 28 - 18 = 10 ft.
The width of the rectangle is the distance between the points (28,12) and (28,4), which is 12 - 4 = 8 ft.
Therefore, the area of the pool is length x width = 10 ft x 8 ft = 80 square feet.
