Answer:
Scale factor: 4:1
Ratio of perimeter: 4:1
Step-by-step explanation:
So basically, there is difference between the ratio of areas and the scale factor.
The area of a shape is equal to the scale factor squared.
We know that the ratio of the 2 areas is 16:1
So, the scale factor must be: [tex]\sqrt[2]{16}: \sqrt[2]{1}[/tex],
Which is basically 4:1
Because the ratio of the scale factor is also equal to the ratio of the perimeter, the ratio of perimeters is also 4:1
