minimum distance (in m) he has to walk starting from his residence and returning to his residence after
visiting both the post office and the bank?

Explanatory Answer
The first thing to realise here is the lengths of the paths.
KN should be equal to LM, giving the length of KO using Pythagoras theorem as 500m
Similarly, the length of HJ=OP=150m and length of GJ=EL=200m, giving the length of HG as 250 m
The shortest path from L to B and then to P (or the other way around would involve) using these hypotenuses
as much as possible instead of the two adjacent sides. The shortest can be visualised as shown below or
multitude of others variations, as there are multiple ways that would make one travel the shortest distance)
