Square Footage of a 3 × 100 ft Rectangle
"Square Footage Calculator" Calculator
How many square feet is 3 × 100 ft?
Answer
A rectangle of 3 × 100 ft covers
300 square feet
Any rectangle 3 ft wide and 100 ft long covers 300 square feet. The order of the sides makes no difference — 3 × 100 and 100 × 3 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:
3 ft × 100 ft
=3 × 100
=300 square feet
3 × 100 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 | 300 square feet |
| Square meters | 27.87 m² |
| Square yards | 33.33 yd² |
| Perimeter | 206 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.
