How many square feet is 11 × 13 ft?

Answer

A rectangle of 11 × 13 ft covers

143 square feet

Any rectangle 11 ft wide and 13 ft long covers 143 square feet. The order of the sides makes no difference — 11 × 13 and 13 × 11 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:

11 ft × 13 ft

=

11 × 13

=

143 square feet

11 × 13 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	143 square feet
Square meters	13.29 m²
Square yards	15.89 yd²
Perimeter	48 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.
