Answer:
All big cities rely primarily on a mix of land uses, but one of the most dominant and essential land uses in urban areas is commercial and residential land use. This combination of uses involves the allocation of space for businesses, offices, retail establishments, and housing. There are several reasons why this combination is predominant in big cities:
Economic Activity: Big cities are often economic hubs, attracting businesses and industries due to the availability of a skilled workforce, transportation networks, and market demand. Commercial land use supports these activities, allowing for the growth and diversification of the urban economy.
Employment Opportunities: Commercial land use creates job opportunities, offering employment for a significant portion of the city's population. Businesses, offices, and retail spaces require a workforce, and residents living in proximity benefit from accessible employment options.
