expanse definition of expanse in the Free Online Encyclopedia.

area, measure of the size of a surface region, usually expressed in units that are the square of linear units, e.g., square feet or square meters. In elementary geometry, formulas for the areas of the simple plane figures and the surface areas of simple solids are derived from the linear dimensions of these figures. Examples are given in the table entitled Formulas for Various Areas Formulas for Various Areas

Plane Figures Area¹
triangle ab/2
parallelogram ab
rectangle ab
square s²
circle πr²

Solids Total Surface Area¹

The areas of irregular figures, plane or solid, can be computed or closely approximated by the use of integral calculus calculus, branch of mathematics that studies continuously changing quantities. The calculus is characterized by the use of infinite processes, involving passage to a limit —the notion of tending toward, or approaching, an ultimate value.
