I have a 7 feet by 10 feet room where I need to put in a small study table as well as a small dining area. Would appreciate suggestions

Given your space constraints, I think it would be best to hang the TV on the wall that is common to the study/living room (just to the right of the door entry). You could get two or three small upholstered chairs for the living area (gives you flexibility in moving them around.) I would have a table surface hung so it can swing out and be used on the wall between the door and the opening to the kitchen. If hung with a hinge attachment so it can be flat on the wall when not in use, you still have space to move around. Backless bar stools could be lined up on that wall when the table is stored flat to the wall, and still be used for more guest seating.

can you suggest how can designs my rooms

room size is 15 square feeet by 16 square feet. north wall has glass windows
