For Ch. 10, Lesson 2, Set III number 4 asks for rectangles with a ratio of 3/4. The key says there are 4 rectangles that have dimensions of 1.5×2. ABHG is correct, but the other three rectangles seem to be wrong. The key lists BDJI (which doesn’t even make a rectangle), CEKI (which is a 1.5×3 rectangle), and DFLJ (which is also a 1.5×3 rectangle). Can you confirm the correct rectangles are ABHG, CDJI, and EFLK? I know it seems obvious, but just want to make sure I’m not missing something here.

You are correct. This looks like a typo. The original solutions manual (titled “Enhanced Teacher’s Guide for Geometry – ISBN: 978-0716756071) had it correct. I have noticed a few places that the answers in the newer solutions manual have typos.
