Find two sides that correspond (like the height of each of them) and divide one by the other to get a ratio. That is the scale you are looking for.

Area is a two dimensional unit. Thus, if two triangles have a scale factor of 16:1 relative to each other, then the ratio of their areas is 256:1. Length is a one dimensional unit. Then, it is correct to say that two triangles with a scale factor of 3:1 will have a ratio of perimeters that is also 3:1.

Consider two similar figures, one being the original figure (A) and the other, the copy (B). Locate any two corresponding sides. the ratio length of copy/length of original is the scale factor

the scale factor is simply the ratio of corresponding sides
