Give me a real-world example of where I may need the area of a polygon (with MORE than 4 sides)

An example could be calculating the area of a soccer field or basketball court which are typically shaped as a regular hexagon or octagon. The area would be necessary for determining the amount of turf or flooring needed for the field or court.

One real-world example where you may need to find the area of a polygon with more than four sides is in the field of urban planning or architecture. When designing a city block or a building complex, it is important to determine the area of the land or the floors to ensure efficient and optimal utilization of space.

For example, imagine you are an architect working on designing a shopping mall. The mall has a complex shape with irregular sides, and you need to calculate the total floor area to determine the commercial space available for shops. By finding the area of the polygon representing the mall's footprint, you can accurately estimate the amount of floor space available for potential renters or determine how to allocate the area for different purposes, such as retail stores, food courts, or common areas. This calculation will help you maximize the use of the available space and ensure the architectural design suits the intended function of the structure.
