In addition to its obvious importance in geometry and calculus, area is related to the definition of determinants in linear algebra, and is a basic property of surfaces in differential geometry.
Udover arealets indlysende vigtighed indenfor geometri og infinitesimalregning, er arealet relateret til definitionen af determinanter i linear algebra, og er en grundlæggende egenskab af overflader i differentialgeometri.
