Formula & Calculations
Formula
Area = Length × WidthWhere:

Calculation Examples
Example 1
Inputs:Length: 12 ft, Width: 10 ft
Result:120 sq ft (13.33 sq yd, 11.15 sq m)
12 × 10 = 120 square feet. Divided by 9 gives 13.33 square yards, and divided by 10.764 gives 11.15 square meters.
Example 2
Inputs:Room 1: 15×12 ft, Room 2: 10×10 ft
Result:280 sq ft (31.11 sq yd, 26.01 sq m)
Room 1 is 180 sq ft, Room 2 is 100 sq ft. Total: 280 sq ft.
