A swimming pool is in the shape of a right rectangular prism. The pool is 40 feet long, 20 feet wide, and 4 feet deep. The cost of repainting the pool is $2.50 per square foot. What is the total cost of repainting the 4 walls and the floor of the pool?

answer: t=3

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
