How much work is done on a gas that expands from A to B along the path shown below?

A gas with an initial volume of 0.2 m³ is heated at constant volume, and the pressure increases from 2×10⁵ Pa to 5×10⁵. Then, it compresses at constant pressure until it reaches a final volume of 0.12 m³. Draw the two processes in the PV diagram below and find the total work done by the gas.
