How many square feet is 8 × 80 ft?

Answer

A rectangle of 8 × 80 ft covers

640 square feet

Any rectangle 8 ft wide and 80 ft long covers 640 square feet. The order of the sides makes no difference — 8 × 80 and 80 × 8 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:

8 ft × 80 ft

=

8 × 80

=

640 square feet

8 × 80 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	640 square feet
Square meters	59.46 m²
Square yards	71.11 yd²
Perimeter	176 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.
