Correct answer: 0

Work done is given by area enclosed in the $PvsV$ cyclic graph or $VvsP$ cyclic graph

Sign of work is positive for clockwise cyclic process for $VvsP$ graph.

Work done in cyclic process = area inside the figure

$W = \dfrac{1}{2} \times ( 30 - 10 ) \times ( 30 - 10 ) = 200kPa - {dm}^{3}$

$= 200 \times 1000Pa - L = 2L - bar = 200J$
