Check my answer. What is the scale factor for the set of similar figures? http://static.k12.com/calms_media/media/1572000_1572500/1572068/1/a0b9acd9a1e1f02d7229754035c3a5c9efb8d129/MS_IMC-141210-110207.jpg

    since the new figure after the transformation is smaller, this means that the scale factor is smaller than 1 (but also positive)

    scale factor = (new length)/(old length) = ???

    you should have done it the other way around 7/20 = 0.35

    basically the smaller figure is 35% of the larger figure
