Let the insect start from point A and walks 15 cm East to reach B, then it turns to its right and walks southwards for another 20 cm. Again, it turns right and walks 4 cm to reach D, then it turns North and walks 20 cm to point E, then finally it turnsto its left and walks 2 cm to stop at point F.
⇒ AF = 15−4−2=9 cm ∴ The insect is 9 cm east with respect to its starting point.
