Question

3s represents the perimeter

The equation P = 3s represents
P of an equilateral triangle with side length s.
proportional relationship between the
perimeter and the side length of
an equilateral
triangle? Explain.

Answer 1

Yes, there is a proportional relationship between the perimeter and the side length of an equilateral triangle. The perimeter is always 3 times the side length of the equilateral triangle.

Answer 2

• Yes

-----------------------------------------

Proportional relationship equation:

• y = kx, where y- dependent variable, x- independent variable, k- constant (coefficient of proportionality)

Our relationship is:

• P = 3s, where P and s are variables and 3 is constant

Since this follows the same logic we can state it is a proportional relationship.
