How many square feet is 20 × 30 ft?

Answer

A rectangle of 20 × 30 ft covers
600 square feet

Any rectangle 20 ft wide and 30 ft long covers 600 square feet. The order of the sides makes no difference — 20 × 30 and 30 × 20 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:

20 ft × 30 ft

=

20 × 30

=

600 square feet

20 × 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 600 square feet
Square meters 55.74 m²
Square yards 66.67 yd²
Perimeter 100 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.
