Deutsch: Fläche / Español: Area / Português: Area / Français: Aire / Italiano: Area
Area is a quantity that expresses the extent of a two-dimensional surface or shape, or planar lamina, in the plane. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

In an environmental context, "area" refers to a specific geographic location or region. Here are a few examples:

1. Protected Area: This refers to a designated area of land or water set aside for conservation purposes, such as national parks, wildlife refuges, and marine reserves.

2. Agricultural Area: This refers to land used for farming, ranching, and other agricultural activities.

3. Urban Area: This refers to a densely populated urban center, typically characterized by high levels of development, commercial activity, and transportation.

4. Forest Area: This refers to a large tract of land covered with trees and undergrowth, typically used for timber production and recreation.

5. Drainage Area: This refers to an area of land that drains into a common watercourse, such as a river or stream.

6. Conservation Area: This refers to an area set aside for the preservation of natural resources, such as wetlands, forests, and wildlife habitats.

7. Coastal Area: This refers to the region along a coast, including the land and water near the shoreline.

In an environmental context, the term "area" is often used to describe a specific geographic region, and to describe the environmental conditions, resources, and activities found within that region.
