A residential area is a place where people live in houses or apartments. It's like a big neighborhood with lots of houses and families. There are usually streets and sidewalks for people to walk and drive on. Residential areas can be in big cities or in smaller towns. In these areas, people usually have their own homes and families, and they have their own personal spaces to relax and enjoy their time. It's a safe place where people can play outside and have fun with their neighbors.
