The area of the walkway around the pool is the difference between the area of the entire rectangle, and the area of the pool. The area of each rectangle is found by multiplying its length and width.

<u>Overall area</u>:
((2x +6) ft) × (10x) ft = (10x² +60x) ft²
<u>Pool area</u>:
((6x -4) ft) × (8 ft) = (48x -32) ft²
<u>Walkway area</u>:
overall area - pool area = ((10x² +60x) ft²) -((48x -32) ft²)
