When you walk through a distance 12 m to east and then 5 m due north, find the magnitude of total displacement and distance covered by you.

Explanation

`bars_(1)=12hati," "bars_(2)=5hatj`
Total displacement `bars=bars_(1)+bars_(2)=12hati+5hatj`
Magnitude of displacement `=|bars|=sqrt(12^(2)+5^(2))=13m`
Total distance covered `=|bars_(1)|+|bars_(2)|=7m`
