[solved] finding magnitude of displacement vector

Silas crawls 1.5 meters due East then crawls 3.2 meters due South. Find the magnitude of the net displacement vector. Make sure you do the following in your answer:

* include correct units
o #.$m o #.$ meters

The question is worth one point, and there is a half point penalty for each incorrect submission.

i got a resultant vector of 3.534m but that was using pythagorean theorem (1.5squared+3.2squared)= 12.49---> square root 12.49=3.53 but i dont know what it means by magnitude...am i doing it right?

Magnitude just means size. It is exactly what you calculated.
