Dear student
when pressure is constant then Work done is calculated by formula
W = P * dV
Hope it helps

Dear friend ,you can easily see that the two triangles are symmetrical.
Po--P2 is double of p3--Po
V2--V1 will also be double of V4--V3
Finally theV4---V3 will be 5L
The area of triangle 120 will give positive work = 1000 joule
The area of triangle 340 will give negative work of 250 joule
So net work done will be 750 joule.
Good regards
Hope you have understood well this is the correct method
Thanks
