How many square feet is 12 × 30 ft?

Answer

A rectangle of 12 × 30 ft covers

360 square feet

Any rectangle 12 ft wide and 30 ft long covers 360 square feet. The order of the sides makes no difference — 12 × 30 and 30 × 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 × 30 ft

=

12 × 30

=

360 square feet

12 × 30 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	360 square feet
Square meters	33.45 m²
Square yards	40 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.
