Answer 1

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.
