A pool measures 15 feet by 17 feet. A cement walkway is added around the pool, to both the width and the length. The area of the pool and the cement walkway is now 483 square feet. What is the width of the cement walkway?

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.
