Help? I have no idea...

Are the quadrilaterals similar? If so, give the scale factor. If not, explain.

castortr0y [4]

These are not similar. For them to be similar, they need to exist in proportion to each other for every single side. The ratio of the 12:9 sides is 4:3 when reduced. The ratio of the other 2 sides is 5:3. They all have to have the same ratio for them to be similar.
