I don't have the pool dimensions or the walkway width from your problem, so I can't pick the correct answer yet. Could you provide the pool length and width and the walkway width (or upload the diagram)?
How to solve it (so you can check quickly):
1. Compute the outer rectangle dimensions: add twice the walkway width to each pool dimension.
2. Area of walkway = area of outer rectangle − area of pool.
3. If dimensions are in feet, convert to square yards by dividing square feet by 9.
Example: if the pool is 12 ft by 20 ft and the walkway is 3 ft wide:
- Outer dimensions = (12+2·3) by (20+2·3) = 18 by 26 → outer area = 468 ft²
- Pool area = 12·20 = 240 ft²
- Walkway area = 468 − 240 = 228 ft² = 228/9 = 25.333… yd² (not one of your choices)
Send the pool and walkway measurements and I’ll compute which choice is correct.
