Question

a body moves 4m towards east and 3m towards north the displcement and distance coverd by the body are

Answer 1

In physics, terminology is important. Displacement isn’t the same as distance, and velocity isn’t the same as speed.

The distance of the particle is how far it traveled, you simply add up how far it
went—3m+4m—and you find the particle traveled a total of 7m.

Answer 2

Hope this helps...
Distance cover by body = 4m+3m =>7m

Displacement =
$\sqrt{ {4 }^{2} + {3}^{2} } \\ \sqrt{16 + 9} \\ \sqrt{25} \\ \ \sqrt{5 \times 5} \\ = 5 m$
