How many square feet is 70 × 80 ft?

Answer

A rectangle of 70 × 80 ft covers
5,600 square feet

Any rectangle 70 ft wide and 80 ft long covers 5,600 square feet. The order of the sides makes no difference — 70 × 80 and 80 × 70 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:

70 ft × 80 ft

=

70 × 80

=

5,600 square feet

70 × 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 5,600 square feet
Square meters 520.26 m²
Square yards 622.22 yd²
Acres 0.1286 acres
Perimeter 300 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.
