I get C. However, I think ther may be a way to get it with just (2). I tried a couple of different ways and got close because we don't really need to know what each term is individually, we just need to know what LW is.
1. Insuff. This is pretty straight forward, L=2 W=4, LW=8. Or L=1 W=5, LW=5.
2. Insuff. We are only given D^2. Like I said, I think there may be a way to use this and get your answer, but I can't seem to do it, so I will stick with my choice. We know that L^2+W^2=D^2, but we still don't know what L and W are.
Together, we know that L+W=6 from (1) so L=W-6. Plug and chug L=W-6 into L^2+W^2=D^2. You get W=4 or 2. If W=4, then L=2, making LW=8. If you pick W=2, then L=4, making LW=8, again. Either value will get your answer.
What is the OA and OE?
