What is area and how is it measured?

Area is the measure of any 2 dimensional region of space. Areas are easily conceptualised as the surfaces of 3 dimensional objects. In the case of certain simple shapes, area is calculated by the product of a region’s length and width (i.e. the 1 dimensional sizes of the area) resulting in squared units of measurement (i.e. cm², m² and ft²).
