Answer:
The total area of the swimming pool is the sum of 5 areas:
Two times a wall with width of 15 ft and depth of 5 ft.
The area of one wall is 15ft⋅5ft=75 ft2
Therefore both walls have an area of 2⋅75 ft2=150 ft2
Two times a wall with length of 30 ft and depth of 5 ft.
Similar calculation like above.
One times a wall with length of 30 ft and width of 15 ft.
The area of this wall is 30 ft⋅15ft=450 ft2
Sum up the all 5 areas. And finally divide this sum by 250 ft2.
