Answer:

21 feet

Step-by-step explanation:

The pool has dimension 15 feet by 17 feet, which is in the form of a rectangle.

The area of the pool = length × width

= 17 × 15

= 255 square feet

Area of the pool and cement walkway = 483 square feet

Area of walkway = area of pool and walkway - Area of pool

= 483 - 255

= 228 square feet

Let's assume that the cement walkway has equal thickness across its perimeter, so that;

the dimension of the pool and the cement walkway = 23 feet × 21 feet

The width of the cement walkway is 21 feet.
