An ideal gas is taken around the cycle ABCA as, 12 P 1 V 1, 6 P 1 V 1, 3 P 1 V 1, P 1 V 1

Work done in the cyclic process = Area bounded (ABCA) = 1 2 × A C × A B = 1 2 × 2 V 1 × 3 P 1 = 3 P 1 V 1 .

The correct answer is:

3 P_{1} V_{1}

Work done in the cyclic process = Area bounded (ABCA)

= \frac{1}{2} \times A C \times A B

= \frac{1}{2} \times 2 V_{1} \times 3 P_{1} = 3 P_{1} V_{1}
