I would go fordifferent rugs if you want to define each area, could be complementary or not depending on colour scheme and furnishings

You can do either. Make sure you size them correctly, especially in the dining area. You want a rug large enough so that when dining chairs are pulled back from table all 4 legs remain on the rug. That is usually 3' bigger all around than the dining table.

Thank you, for the comments and the pics. The additional 3 feet around the table really surprised me, had no clue.
