How many square feet is 9 × 100 ft?

Answer

A rectangle of 9 × 100 ft covers
900 square feet

Any rectangle 9 ft wide and 100 ft long covers 900 square feet. The order of the sides makes no difference — 9 × 100 and 100 × 9 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:

9 ft × 100 ft

=

9 × 100

=

900 square feet

9 × 100 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 900 square feet
Square meters 83.61 m²
Square yards 100 yd²
Perimeter 218 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.
