Formula:

The formula for calculating square footage is simple: Length × Width = Square Footage.

  • Length: The measurement of one side of the area (e.g., 20 feet).
  • Width: The measurement of the adjacent side of the area (e.g., 15 feet).
  • Square Footage: The total area covered by the length and width (e.g., 20 ft × 15 ft = 300 sq ft).

Ensure both measurements are in the same unit (feet, meters, or yards) for an accurate result in square units.
