Answer: The last option.
Step-by-step explanation:
1. By definition the ratio of the perimeter is the same as the scale factor.
2. Keeping this on mind, you can calculate the scale factor as shown below:
[tex]sf=\frac{8}{6}\\sf=\frac{4}{3}[/tex]
3. You can rewrite it as following:
4:3
4. Therefore, the ratio of the perimeter is 4:3
