In the given problem, we are asked to find the constant of proportionality between the perimeter and the side length of a square.

We can calculate the constant by taking the ratio of the perimeter to the side length. Based on the table:

$\text{Perimeter} = 8 \, \text{inches}, \quad \text{Side length} = 2 \, \text{inches}$

The formula for the perimeter of a square is $P = 4 \times \text{side length}$.

Thus:

$\frac{\text{Perimeter}}{\text{Side length}} = \frac{8}{2} = 4$

This same ratio holds for the other pairs of values in the table:

• $\frac{16}{4} = 4$
• $\frac{24}{6} = 4$

Therefore, the constant of proportionality is 4.
