In triangle AOD, AE is median.
So,ar(AOD)=2*10 sq.cm(Median divides the triangle into 2 triangles of equal area.)
Therefore, ar(ABCD)=4*2*10 sq.cm=80 sq.cm( Since diagonals of parallelogram divides it into 4 triangles of equal areas.)
So,ar(AOD)=2*10 sq.cm(Median divides the triangle into 2 triangles of equal area.)
