Find out the work done in the given graph. Also draw the corresponding T -V curve and P-T curve.

Explanation

Since in `P-V` curves the area under the cycle is equal to work done, therefore work done by the gas is equal to `p_(0) V_(0)`.
Line `AB` and `CD` are isochoric line, `BC` and `DA` are isobaric line.
`:.` The `T - V` curve and `P -T` curve are drawn as shown in the figure.
