Starting from a point, Kalidas walked $12\text{m}$ North, he turned right and walked $10\text{m}$, he again turned right and walked $12\text{m}$, then he turned left and walked $5\text{m}$. How far is he now and in which direction from the starting point?

Let us trace the path step-by-step from the origin $(0,0)$:
1. Walks $12\text{m}$ North $⟹$ Position is $(0,12)$.
2. Turns right (East) and walks $10\text{m}$ $⟹$ Position is $(10,12)$.
3. Turns right (South) and walks $12\text{m}$ $⟹$ Position is $(10,0)$.
4. Turns left (facing South, a left turn leads East) and walks $5\text{m}$ $⟹$ Final position is $(10+5,0)=(15,0)$.

Thus, he is at a total distance of $15\text{m}$ directly towards the East from the starting point.
