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).

Area of a Square= Side length x Side length
Answer = (Side length x Side length) square area
Abbreviations of unit area: ft², in², yd², cm², mm², m²
