How many square feet is 31 × 39 ft?

Answer

A rectangle of 31 × 39 ft covers
1,209 square feet

Any rectangle 31 ft wide and 39 ft long covers 1,209 square feet. The order of the sides makes no difference — 31 × 39 and 39 × 31 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:

31 ft × 39 ft

=

31 × 39

=

1,209 square feet

31 × 39 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 1,209 square feet
Square meters 112.32 m²
Square yards 134.33 yd²
Acres 0.0278 acres
Perimeter 140 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.
