The Following Table Shows the Relationship Between $s$ , the Side Length of an Equilateral Triangle

Short Answer

The following table shows the relationship between $s$ , the side length of an equilateral triangle, $p$ , the perimeter of the triangle, and $A$ , the area of the triangle.

If $p$ is a linear function of $\mathrm{s}$ , give its rate of change. If it is not linear, enter "not linear".
