elia 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?
To find the area of the pool, we need to find the length and width of the rectangle.
The length of the rectangle can be found by subtracting the x-coordinates of two adjacent corners:
Length = 28 - 18 = 10 ft
The width of the rectangle can be found by subtracting the y-coordinates of two adjacent corners:
Width = 12 - 4 = 8 ft
To find the area of the rectangle, multiply the length by the width:
Area = Length x Width = 10 ft x 8 ft = 80 sq ft
Therefore, the area of Elia's pool is 80 square feet.
