Okay kiddo, a business park is like a big playground for grownups who work in offices, factories or warehouses. Instead of swings and slides, there are buildings where grownups go to work.
Imagine a big piece of land where lots of companies build their own special buildings where they do their work. Some companies have offices where people sit at desks, answer phones and send emails. Other companies have big factories or warehouses where they make things or store things.
Business parks have lots of different buildings, like a mall has lots of different stores. People who work in the business park can go from building to building to visit different companies.
Sometimes, business parks also have things like sidewalks, landscaping and benches for people to use when they take a break from work. It's like having a big, fancy playground for grownups who work.
