Not sure what areas you mean, but the work ( W = ∫ p d V) on the system for path A is the area under the projection of A onto the V-axis, and the work done on the system for path B is the area under the projection of B onto the V-axis. The area under A is greater than B, thus more work is done on the system for process A than B. ireland 8pm curfew
