Answer

A rectangle of 11 × 31 ft covers
341 square feet

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 × 31 ft

=

11 × 31

=

341 square feet

11 × 31 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 341 square feet
Square meters 31.68 m²
Square yards 37.89 yd²
Perimeter 84 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.
