Distance is just the total amount he traveled (3.5 + 2 + 4.5 = 10m).
Displacement is the distance between his starting point and ending point (you may want to draw a picture for this). What you get is that he traveled a total of 8m east and 2m south.
Therefore, his total displacement is the length of the hypotenuse of a right triangle with sides 2 and 8 (= 8.25m).
