Square Footage of a 13 × 30 ft Rectangle
Square Footage Calculator
How many square feet is 13 × 30 ft?
Answer
A rectangle of 13 × 30 ft covers
390 square feet
Any rectangle 13 ft wide and 30 ft long covers 390 square feet. The order of the sides makes no difference — 13 × 30 and 30 × 13 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:
13 ft × 30 ft
=13 × 30
=390 square feet
13 × 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 | 390 square feet |
| Square meters | 36.23 m² |
| Square yards | 43.33 yd² |
| Perimeter | 86 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.
