Unofficial: <R7.f> Clarification Request:"As cut from a single 12"*24" sheet" ref. area or perimeter

I would say that it must be of a shape that could have been cut from a single sheet of that size based on a similar rule in the VEXU version of the game with the rule modifications found in Appendix E, but it would not have to start as a single sheet because you could just cut the sheet into two.
