To solve the problem of calculating the width of the entire swimming pool (AD), we can analyze the given diagram. 

The swimming pool consists of a rectangular section (deep pool) and a semicircular section (shallow pool).

- The width of the rectangular section (deep pool) is indicated by the line **CD**, which is given as 16 meters.
- The semicircular section is attached to one end of the rectangle, and its diameter is also equal to **CD**, which is 16 meters.
- Thus, the radius of the semicircular section is half the diameter, so it is \( r = \frac{16}{2} = 8 \) meters.

### Total Width (AD):
- From point **A** to **D** is the total width of the swimming pool, which includes the width of the rectangular section and the radius of the semicircular section on both sides.
- Hence, the total width \( AD = 16 \, \text{m} + 8 \, \text{m} = 24 \, \text{m} \).

So, the width of the entire swimming pool (AD) is **24 meters**.
