1 - tells me that the side of the square is 10. Insufficient.
2 - tells me that AB*height of ABE = 10*2
Taking 1&2 together, we have the height = 2. Still we do not know DE since it will depend on E being inside or outside the square.
Hence, answer E
OA, please .....?

Stmt 1: Area of square =100, hence sides = 10, insufficient to calculate DE
Stmt 2: Area of triange = 10, Hence height = 2, insufficient to calculate DE
Putting them together: Not enough to calculate DE as no information is given whether E is inside the square or outside.
My answer E.
