What is the are of parallelogram ABCD?
[1] AB = BC = CD = DA = 1
[2] AC = BD = sqrt(2)
I think the answer is B, because we know the diagonal of a square is s*sqrt(2), where s = the length of a side of the square, and if we know the two diagonals of this parallelogram are equal then we know it is a square, right? Can we not assume that the side is 1 given that we know the diagonal?
The OA is: C

I agree.
Stmt 1: tells us that all sides are equal so this could be a square or a rhombus. Insuff
Stmt 2: tells us that both diagonals are equal so this must be a square. The diagonals of a square equal S=Sqrt(2) where S is the side, so the sides are 1 and the area is 1.
