An Ideal Gas Undergoes the Process A→b→c→a Shown in the PV

An ideal gas undergoes the process a→b→c→a shown in the pV diagram.In this figure,P_a = P_c = 3.60 × 10⁵ Pa,V_b = V_c = 68.00 L,V_a = 35 L,and P_b = 5.60 × 10⁵ Pa.How much work is done on the system in this process?

A) -2300 J
B) -3300 J
C) -2800 J
D) -3800 J
E) -3000 J
