Room Boundaries - number lines

I read the perimeter of 11 rooms:

no.3 room has 6 sides —> I find 8 lines ----> why? —> How to find the Boundaries lines?
nr.1 room has four sides —> I find 6 lines ----> why? —> How to find the Boundariesr lines?

You should highlight your edges one by one to check what is going on, like so:

You should upload your rvt file so that we can have closer look at it.

You’re getting multiple curves due to the nature of your wall joins and an other wall which touches that space. You should look at this post for a possible solution and also read @Konrad_K_Sobon explanation which is more detailed than mine:

Room.Boundaries - more curves than walls..?

This is caused by different Room bounding conditions. For example: [Capture]     [Capture]     [Capture]       You are probably noticing a pattern there. Revit has trouble recognizing a wall by its “short” face. Also, in case there was a small break in-between the walls, rooms will automatically fill in the gap to enclose themselves, but in that case - and understandably - there is no wall associated with that particular edge. Does that make sense? However, what is possible is what …

Thanks for collaboration
I solved this way:
