The last area ABGF is not quite right. It would be more accurate to say ABG(F+0.2) or to mark the node to the right of F as F'. However, I think you have calculated the required area anyway.
I am confused at how you have determined the limits of integration and this may be where your main error is.
For BCFG the limits should be V= 1.0 to V = 3.0
For DAFE the limits should be V= 0.4 to V = 1.2
