What does the term "area" refer to in terms of polygons?

1. The total length around the polygon

2. The number of square units covered by the polygon

3. The distance across the polygon

4. The perimeter of the polygon

The correct answer is: The number of square units covered by the polygon

The term "area" specifically refers to the amount of space that a shape occupies, measured in square units. For polygons, the area quantifies how much two-dimensional space is contained within the boundaries of the polygon. Thus, saying that the area is the number of square units covered by the polygon accurately captures this concept. In contrast, the other choices refer to different geometric concepts. The total length around a polygon is referred to as the perimeter, while the distance across the polygon calls to mind different aspects of measurement, such as diameter or breadth, depending on the context. Lastly, the perimeter itself is a distinct measure from area, representing the sum of all the sides of the polygon. Therefore, the correct understanding aligns perfectly with the definition provided in your answer.
