Explanation:

Eastern Europe is the region of the European continent between Western Europe and Asia. There is no consistent definition of the precise area it covers, partly because the term has a wide range of geopolitical, geographical, ethnic, cultural, and socioeconomic connotations. Russia, located in Eastern Europe, is both the largest and most populous country of Europe; spanning roughly 40% of the continent's total landmass, with over 15% of its total population.
