computes the area for a `LinearRing`

, `Polygon`

or
`MultiPolygon`

. Undefined for all other geometry types (returns zero).

## Arguments

- wkt
Character. OGC WKT string for a simple feature geometry.

## Value

Numeric scalar. Area of the geometry or `0`

.

## Note

`LinearRing`

is a non-standard geometry type, used in GDAL just for geometry
creation.
