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.

Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
