There appears to be a discrepancy with this quetion, as this question is listed on the OG guide 2022 under the label
Algebra Second degree equations , so I would guess, that this type of problems can actually be tested on the GMAT Focus. However, the tags under this problem on GMAT Club is "Geometry", and it really tests geometry concepts. So, should I worry about this problem while studying for the GMAT Focus, or should I just skip it?
While specific geometry knowledge is not tested on GMAT Focus, not everything involving shapes, volumes, or areas requires specialized geometry knowledge. The area of a square or rectangle, the volume of a cube or rectangular solid, and the Pythagorean theorem are not considered specific geometry knowledge by the GMAT and can still be tested. Moreover, a question can involve shapes but test another area, such as combinations or other topics. There are several
questions involving these concepts in the GMAT Prep Focus mocks.
Some aspects of coordinate geometry are also tested on GMAT Focus under the Functions tag.
The question at hand, although involving fairly simple geometry concepts, leans more towards algebra. So, I wouldn't dismiss this question with 100% certainty.
