How many square feet is 18 × 28 ft?
Answer
A rectangle of 18 × 28 ft covers
504 square feet
Any rectangle 18 ft wide and 28 ft long covers 504 square feet. The order of the sides makes no difference — 18 × 28 and 28 × 18 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:
18 ft × 28 ft
=18 × 28
=504 square feet
18 × 28 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 | 504 square feet |
| Square meters | 46.82 m² |
| Square yards | 56 yd² |
| Perimeter | 92 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.
