Dear Student
 
WHEN he starts from 30 m north then 20 m east then we can say that resultant displacement is sqrt(30^2+20^2)=10 sqrt(13) m
by addition of triagle vector.
he then finally moves 30 √2 m  in south - west  
so, displacement=final position-initial position
=30 √2 m  in south - west  - 10 √13 in south west
= 42.43 m -36.05 m
=6.38 m
