Official Key: The correct answer is (E). You could piece together the panes into either a single

column (or row) of 8 panes or into 2 adjacent columns (or rows) of 4 panes each. In the

first case, the door’s perimeter would be 18. In the second case, the door’s perimeter

would be 12. Thus, statement (1) alone is insufficient to answer the question. Statement

(2) alone is insufficient for the same reason. Both statements together still fail to

provide sufficient information to determine the shape (or perimeter) of the door

Am I wrong or this Peterson's key is wrong?

Both 1 and 2 say the same thing

they can be 4x2 or 8x1 same areas but different perimeters

we may know the answer or we may not...perhaps this is where you are getting stuck?

you are saying C proves that we can't answer the question not that C answers the question. is that correct?

however, we may be able to answer the question, we just don't have enough information
