The person goes 30 m in north, and then 20 m in east and then 30√2 m in south west. Now, if we draw this diagram on a paper, then it would form a right-angled triangle kind of thing. So, the final position would lie on the hypotenuse of the triangle. Now, studying the diagram a more, we get,


length of hypotenuse = root(302 + 202 ) = 10√13 m


net displacement vector = 10√13 - 30√2


==> 42-36.6


==>5.4 m
