Rectangle: length (ft) × width (ft) → area in square feet.
Square feet = length(ft) × width(ft); the second figure multiplies that by 0.092903 as a quick ft²→m² conversion (decimal feet assumed). Not a survey-grade projection.
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
