Why is the main reinforcement provided on the longer side of raft footing?

Since the dimentions and magnitude of the 2nd is more than the first one, the settlement would not be same roughly. Bcoz the dimension are twice the 1st one, Magnitude is 4 times the 1st one. So bcoz of this, obviously the 2nd footing will be settled more.

The longest span is in more critical section due to which main reinforcement is provided on the longer span. The longest span has to bear a higher bending moment. This is because the uplift pressure from the soil below will be equal in all locations, but the moment developed at the longer span will be higher because of a long arm. Its a uniformly distributed load and so it produces a larger moment on a longer beam. Thus, the main reinforcement is provided in longer span.
