The usable area of a floor is called:
Show Hint
- Carpet area
- Plinth area
- Surface area
- Built-up area
The Correct Option is A
Solution and Explanation
Carpet area is the net usable area within a building, measured from wall to wall.
It excludes wall thickness, balconies, corridors, staircases, and other common areas.
Plinth area includes carpet area plus wall thickness and other covered spaces.
Built-up area further includes balconies and external walls.
Surface area is a general term and not specifically used to denote usable floor space. Hence, the usable area of a floor is called carpet area.
Final Answer: \(\boxed{\text{Carpet area}}\)
