How many square feet is 3 × 3 ft?

Answer

A rectangle of 3 × 3 ft covers

9 square feet

Any rectangle 3 ft wide and 3 ft long covers 9 square feet. The order of the sides makes no difference — 3 × 3 and 3 × 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 × 3 ft

=

3 × 3

=

9 square feet

3 × 3 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	9 square feet
Square meters	0.84 m²
Square yards	1 yd²
Perimeter	12 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.
