Concept:Use the directions (N, S, E, W) and track net displacement along north-south and east-west axes.
Explanation:Start at origin.
1. 25 m South: position = (0, -25).
2. Turn left (now facing East), walk 20 m: position = (20, -25).
3. Turn left (now facing North), walk 25 m: position = (20, 0).
4. Turn right (now facing East), walk 15 m: position = (35, 0).
Net displacement: 35 m East of starting point.
Answer:35 meters East.
