A girl walks 200 m towards east and then she walk 150m towards North.
If you are talking about distance then distance = 200 + 150m = 350m
If you are talking about distance from the starting point, that is, displacement then we have to calculate it by Pythagoras theorem. (Refer the attachment)
By Pythagoras theorem,
displacement = √(200² + 150²)
=> displacement = √{40000 + 22500}
=> displacement = √62500
=> displacement = 250m
Hence its Distance from the starting point is 250m
Hope it helps dear friend ☺️✌️

His answer is verified by experts so he is definitely right ^_^
absolutely right ans
displacement is shortest path where as distance is total path. so here distance is 350m whereas displacement is 250m
nice
