If we take east as x-axis and north as y-axis,then displacement =20i^+10j^. So , magnitudeof displacement a=√400+100=10√5=22.5m .

Dear student,
Please find the solution to your problem.
If we take east as x-axis and north as y-axis,then displacement
= 20i + 10j.
So, magnitude of displacement a = √(400+100) = 10√5 = 22.5m
Thanks and regards,
Kushagra
