Explanations:A metropolitan area is a large urban area that consists of a central city and its surrounding suburbs, which are economically and socially integrated. The term "metropolitan area" is used to describe a region where the central city and its surrounding areas form a single economic and social unit. This integration is often characterized by a high population density, diverse economic activities, and extensive transportation networks that connect the central city with its suburbs.
In the context of the question, Delhi along with Faridabad, Ghaziabad, Noida, and Gurgaon forms a metropolitan area. These cities are not independent entities but are part of a larger urban region that functions as a single economic and social unit. The population density, economic activities, and transportation networks in this region are interconnected, making it a metropolitan area.
It is important to distinguish a metropolitan area from other urban classifications such as satellite cities, smart cities, and rural areas. A satellite city is a smaller city that serves a larger city, often providing residential space for commuters. A smart city, on the other hand, is a city that uses information and communication technologies to enhance the quality and performance of urban services. Rural areas are characterized by low population density and agricultural activities, which are not present in the given cities.
Understanding the concept of a metropolitan area is crucial for comprehending urban geography and the integration of urban regions. This knowledge is particularly relevant for competitive examinations that test knowledge of geography and urban planning.
