How many square feet is 12 × 20 ft?

Answer

A rectangle of 12 × 20 ft covers

240 square feet

Any rectangle 12 ft wide and 20 ft long covers 240 square feet. The order of the sides makes no difference — 12 × 20 and 20 × 12 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:

12 ft × 20 ft

=

12 × 20

=

240 square feet

12 × 20 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	240 square feet
Square meters	22.3 m²
Square yards	26.67 yd²
Perimeter	64 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.
