The "Area of Country" refers to the total land surface of a nation, measured in square kilometers or square miles. This measurement includes all types of terrain, such as mountains, forests, and bodies of water. The area can influence a country's population density, natural resources, and economic activities. Different countries have varying areas, with some being vast like Russia, which is the largest country in the world, while others are much smaller, like Monaco. Understanding the area of a country helps in geographical studies, urban planning, and environmental management.
