Coerce area to lines.

Snap your cutting lines to those (vertexsnapping in your example). Use polygon as anchor to keep polygon as is. (topologybuilder is also used for this as the later versions have tolerance)

Build area.

Hi here is an workbench

Using Topologybuileder or Interscetor.

Crucial is of course Snapping and snappingtypes. (depends on quality on the inputobjects. In my case i drew your examples in Inkscape so it was not topologicaly tight))
