How many square feet is 40 × 80 ft?
Answer
A rectangle of 40 × 80 ft covers
3,200 square feet
Any rectangle 40 ft wide and 80 ft long covers 3,200 square feet. The order of the sides makes no difference — 40 × 80 and 80 × 40 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:
40 ft × 80 ft
=40 × 80
=3,200 square feet
40 × 80 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 | 3,200 square feet |
| Square meters | 297.29 m² |
| Square yards | 355.56 yd² |
| Acres | 0.0735 acres |
| Perimeter | 240 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.
