Answer:
It would be 10 steps.
Explanation:
Assume that child started r his journey in NORTH, after walking 10 steps he will turn 90° left and will walk 10 steps towards WEST. Again he will turn 90° left to walk 10 steps towards south.
He walked 30 steps. His path now represents a square, opposite sides of it are equal, hence
MAXIMUM DISPACEMENT:- 10steps
