<P> The area of a shape can be measured by comparing the shape to squares of a fixed size . In the International System of Units ( SI ) , the standard unit of area is the square metre ( written as m ) , which is the area of a square whose sides are one metre long . A shape with an area of three square metres would have the same area as three such squares . In mathematics , the unit square is defined to have area one , and the area of any other shape or surface is a dimensionless real number . </P>
