The problem involves determining the shortest route for a child to run and touch each of the three walls of a rectangular schoolyard, starting at point \( S \), then returning to point \( S \).

### Key points:
- The rectangular yard is \( 16 \, \text{yd} \times 12 \, \text{yd} \).
- The starting point \( S \) is 4 yards along from point \( A \) on the \( AB \) side, making it 12 yards away from \( B \) horizontally and 12 yards away from \( D \) vertically.

To minimize the running distance, we can use the concept of **reflection**. The idea is that instead of running directly to each wall and returning, we reflect the diagram and consider running straight to a reflected point on the extended walls, minimizing the overall distance.

I'll work on determining the optimal route mathematically by analyzing the distances from \( S \) to each of the walls (points \( C \), \( D \), and \( B \)) and determining the shortest overall path. Let me calculate that for you.The shortest route for the children to take is approximately **40.97 yards**. This is based on touching each of the walls and returning to the starting point \( S \), by following an optimized path rather than directly running back and forth.

Would you like further details on how this route was optimized?

Here are some related questions:
1. How can the reflection method be applied in other geometric problems?
2. What are some real-life examples where finding the shortest path is important?
3. Can the distance formula be applied to three-dimensional problems?
4. How would the problem change if the yard's dimensions were different?
5. How could we generalize this solution for any starting point along a rectangle?

**Tip:** In many optimization problems, the reflection method is useful for minimizing distances when multiple points need to be reached.

Some children are playing a game in a rectangular schoolyard ABCD that is 16 yards by 12 yards. They start at point S, which is 4 yards along the 16-yard wall AB. They have to run and touch each of the other three walls and then get back to S. What is the shortest route for them to take?

Solve an optimization problem involving the shortest route in a 16-yard by 12-yard rectangular schoolyard. Students will apply geometry, distance formulas, and the Pythagorean Theorem to determine the minimal path for a child starting at a specific point in the schoolyard. Suitable for Grades 9-12.
