given: the poo is
16ft WIDE
+8ft LONG
4ft DEEP
the surface area of the pool bottom: multiply the length by the width
16ft%2A8ft=128ft%5E2
the surface area of the pool walls: for rectangular pools, add the length and width, and multiply by twice the depth

%2816ft%2B8ft%29%2A2%2A4ft=24ft%2A8ft=192ft%5E2
Add the surface area of the pool bottom and the surface area of the pool walls. This will give you the total pool area in square feet.
128ft%5E2%2B192ft%5E2=320ft%5E2...your answer
