How many square feet is 9 × 12 ft?
Answer
A rectangle of 9 × 12 ft covers
108 square feet
Any rectangle 9 ft wide and 12 ft long covers 108 square feet. The order of the sides makes no difference — 9 × 12 and 12 × 9 are the same area.
How the Square Footage Is Calculated
Square feet = width (ft) × length (ft)
Area is a product, not a sum: a rectangle holds as many one-foot squares as its width multiplied by its length. Put this rectangle into it:
9 ft × 12 ft
=9 × 12
=108 square feet
9 × 12 ft in Other Units
The same rectangle expressed the other common ways. The perimeter is the figure to use for skirting, edging or fencing — and it is what tells this rectangle apart from other sizes with the same area.
| Square feet | 108 square feet |
| Square meters | 10.03 m² |
| Square yards | 12 yd² |
| Perimeter | 42 ft |
Note: this is floor area. Wall area is height × length for each wall, and a room that is not a plain rectangle has to be split into rectangles first and added up.
