Strategy:
 Successive transformations in a cyclic process result in no change in net internal energy (). The net work done is the area enclosed within the  loop.

Step 1: Analyze the P-V plot
The process is a clockwise triangle on a  vs  diagram.
The area of a triangle .

Step 2: Calculation
Base () .
Height () .
Area .
Since the cycle is clockwise, the gas does net work on the surroundings.
