@Bittu. Unfold the room. Supposing that the 4x5 plane is the floor, then the adjacent walls are 3x4 and 3x5:
+----+ | | | | +----+ | | +----+ or +----+--+ | | | | | | +----+--+ The paths between opposite corners of the room map into paths from opposite corners of these figures. The shortest path in each figure is the diagonal. One is of length sqrt(5^2 + 7^2) and the other is of length sqrt(4^2 + 8^2). The former is the shorter.
