Answer:
50m
- step a) when he walks 30m in south and turning right means moving west 30m.
- step b) when he turns left means moving in south from initial point and walks 20m.
- step c) again turning left means moving II (parralell) to to the line in opposite direction of second path of 30m.
- step d) as watching the diagram the last point is the straight line. if we add them both the ans comes to be 50m.
hope you understand this.
