+## area
+
+Takes one or more features and returns their area in square meters.
+
+**Parameters**
+
+-   `geojson` **[GeoJSON][1]** input GeoJSON feature(s)
+
+**Examples**
+
+```javascript
+var polygon = turf.polygon([[[125, -15], [113, -22], [154, -27], [144, -15], [125, -15]]]);
+
+var area = turf.area(polygon);
+
+//addToMap
+var addToMap = [polygon]
+polygon.properties.area = area
+```
+
+Returns **[number][2]** area in square meters

+This module is part of the [Turfjs project](http://turfjs.org/), an open source
+module collection dedicated to geographic algorithms. It is maintained in the
+[Turfjs/turf](https://github.com/Turfjs/turf) repository, where you can create
+PRs and issues.
+
+### Installation
+
+Install this module individually:
+
+```sh
+$ npm install @turf/area
+```
+
+Or install the Turf module that includes it as a function:
+
+```sh
+$ npm install @turf/turf
+```
