distance he travelled = 24+7 = 31m
displacement is the shortest distance
when we draw diagram we get a triangle(right angled) and the hypotenuse will be the displacement. so, by pythagoras theorem
so hyp² = 24² + 7²
hyp = √576+49
hyp = √625
hyp = 25
so the displacement = 25m

24m towards south= -24j
7m east = 7i
displacement=7i-24j
distance= √(7)²+(-24)²
=√49+576
=√625
=25m
or displacement=25(i-j)m
Sorry distance=24+7=31m
