How to find displacement in vector diagram?

    how to find displacement in vector diagram???

    My homework question states :
    "Mr. Hinsley walks north 252 m, east 512 m, south 35.5 m and finally west 256 m. What is the total distance traveled? What is his displacement?"

    I got that the total distance = 1096 m
    However i am having trouble finding the displacement. i made a vector diagram but don't quite know how to use it to find the displacement.




    ! combined north and south. i also combined east and west. i came to the conclusion that he ended up at 176.5 m north and 256 m east. i just don't know what to do from here.
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Each leg of the journey is a displacement. Displacement, as you've realized, is a vector.
    The sum of all the displacement vectors is the total displacement.
    Do you know how to add vectors?

    Draw a line from the origin to your point. You should now see a right triangle. Use the pythagorean theorem.
