Example Determining Whether Relationships are Proportional Using Tables
The diagram shows a series of squares drawn on graph paper. The side length and perimeter of each square are labeled.
Use the diagram to complete the table. Draw the next few squares as needed. Write all the ratios in simplest form.
Is the relationship between the perimeter and side length of a square proportional? How do you know?
Since all the ratios are equivalent, the relationship between side length and perimeter of a square is proportional.
