Correct answer
200

Step-by-step explanation

Work done is given by area enclosed in the P vs V cyclic graph or V vs P cyclic graph

 Sign of work is positive for clockwise cyclic process for V vs P graph.

Work done in cyclic process = area inside the figure

W=12×(30-10)×(30-10)=200 kPa-dm3

=200×1000 Pa-L=2 L-bar=200 J
