- Area( <Point>, ..., <Point> )
- Calculates the area of the polygon defined by the given points.
- Example:
Area[(0, 0), (3, 0), (3, 2), (0, 2)]yields 6.
- Area( <Conic> )
- Calculates the area of a conic section (circle or ellipse).
- Example:
Area[x^2 + y^2 = 2]yields 6.28.
- Area( <Polygon> )
- Calculates the area of the polygon.
Note:
- for Polygons, the absolute value of the Algebraic Area is calculated (which gives unexpected answers for self-intersecting polygons)
- In order to calculate the area between two function graphs, you need to use the command IntegralBetween.
- See also the
Area tool.
