Question

Each triangle is equilateral. Is the relationship between the perimeter and the side length of the equilateral triangles proportional? Explain

Answer 1

Answer: Yes, it’s proportional

Explanation:

By calculating and comparing the unit rate of the perimeter to the side length for the given triangles. Follows that the 2 quantities are proportional.

Answer 2

We have the following:

`\begin{gathered} s=1,p=3\cdot1=3 \\ s=2,p=3\cdot2=6 \\ s=3,p=3\cdot3=9 \end{gathered}`

The perimeter is also proportional because it increases to the same measure
