# Length Command

From GeoGebra Manual

- Length[Vector]
- Yields the length of the vector.
- Length[Point A]
- Yields the length of the position vector of the given point .
- Length[Function, Number x1, Number x2]
- Yields the length of the function graph in the interval [
*x1, x2*]. - Length[Function, Point A, Point B]
- Yields the length of the function graph between the two points
*A*and*B*. - Note: If the given points do not lie on the function graph, their x‐coordinates are used to determine the interval.
- Length[Curve, Number t1, Number t2]
- Yields the length of the curve between the parameter values
*t1*and*t2*. - Length[Curve c, Point A, Point B]
- Yields the length of curve
*c*between two points*A*and*B*that lie on the curve. - Length[List]
- Yields the length of the list which is the number of elements in the list.

**Note:** Also see tool Distance or Length.
