IMHO we can not calculate the area of parallelogram using diagonals.
The only thing w know for sure is that the diagonals bisect each other.
But, I think the area will depend on the angle at which they bisect.

Answer: E

Question : What is the area of a parallelogram with diagonals x and y?

Statement 1: x = 10

Not sufficient

Statement 1: y = 8

Not sufficient

COmbining the two statements

The length of two diagonals is not sufficient to calculate the area of the parallelogram because the angle between th etwo diagonal is still a variable hence area will have no unique value hence

NOT SUFFICIENT

Answer: option E
