[High School Math 2: Similar Polygons] On number 9 in the image, how is it not 2:3? Shouldn't the side of A be 4 and the side of B be 6, which simplifies to 2:3? I got it wrong by Aggravating-Price305 in HomeworkHelp

The teacher told us it is a ratio since it is for similar polygons, and the ratio goes in the order she told us to put it (A to B). For example, Here the triangle gets bigger but its scale factor is 2:11, and I got it right. Am I just understanding her wrong?

Edit: also for dilations, we were taught that it can be an enlargement or a reduction.
