Understanding the Square Footage
To understand how to calculate square footage we must first begin with the definition of area. An area is the size of a two-dimensional surface. The area of a square is the space contained within a set of lines. These lines should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m).
The Formula
Area of a Square = Side length x Side length
Answer = (Length x Width) square area
