Answer 2

Answer:

The tile border around the kiddie pool is 72 square feet.

Step-by-step explanation:

To find the area of the tile border, you take the area of the entire rectangle (both inner and outer) and subtract the inner rectangle from it.

Area of entire rectangle: 18 * 9 = 162 ft^2

Area of inner rectangle: 15 * 6 = 90 ft^2

Area of tile border: 162 - 90 = 72 ft^2

The tile border around the kiddie pool is 72 square feet.
