How many square feet is 9 × 10 ft?

Answer

A rectangle of 9 × 10 ft covers

90 square feet

Any rectangle 9 ft wide and 10 ft long covers 90 square feet. The order of the sides makes no difference — 9 × 10 and 10 × 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 × 10 ft

=

9 × 10

=

90 square feet

9 × 10 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	90 square feet
Square meters	8.36 m²
Square yards	10 yd²
Perimeter	38 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.
