Easy problem (should be) with lines and shapes

[gplanelles]

I have four separate lines, 2 parallels, 1 half-circle (obtained from a circle cut with a vertical line - with menu 'Arrange/Combine/Cut') and a slanted line.
I want to create a closed shape with one rounded end.

All lines are placed as needed. I select all my lines and I want now to create one shape in order to fill it with one flat color.

I have tried several combinations of 'Arrange/Group', 'Arrange/Join' or 'Arrange/combine' and I never obtain a 'fillable' shape.

Sure I'm wrong, but where ?

Thanks for your help.
