How many square feet is 42 × 100 ft?

Answer

A rectangle of 42 × 100 ft covers
4,200 square feet

Any rectangle 42 ft wide and 100 ft long covers 4,200 square feet. The order of the sides makes no difference — 42 × 100 and 100 × 42 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:

42 ft × 100 ft

=

42 × 100

=

4,200 square feet

42 × 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 4,200 square feet
Square meters 390.19 m²
Square yards 466.67 yd²
Acres 0.0964 acres
Perimeter 284 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.
