Let us suppose A be the starting point. The man runs 4 km towards north and reaches at point B. Now he runs 20 km towards east and reaches at point C. Finally he runs 4 km towards south and reaches at point D. We have to find the length of AD.
From the attached diagram, we can see that
AB = 4
BC= 20
CD = 4
This is a rectangle. Hence, we can say that
AD = CD
AD = 20
Therefore, the man is 20 km far from his starting point.
