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.

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
