What does a scale factor between two similar figures tell you about the relationships between the length and area measures of the figures?

Question

The relationship is that you use the l&w to find the scale factor. you can
make L&W ratios for each figure, then you divide both of the ratios to get the scale factor.

i found my answer

Answer 1

The scale factor between two similar figures tells you that the ratio of the lengths and widths of the figures is the same, and that the ratio of the areas of the figures is the same as the square of the scale factor.
