S1- DE>EC
Area of tr. ADE=$$\frac{1}{2}$$ xDExAD
Area of tr. ACE=$$\frac{1}{2}$$ xECxAD
Since DE>EC, Area of tr. ADE > Area of tr. ACE
Sufficient.

S2 - AC>AE.
Insufficient.

statement 1- DE>EC, sufficient. (Using formulae for triangle=1/2*base*height)
statement 2- insufficient.

1. As explained above, this relation is sufficient to compare the area.
2. This information is redundant. Diagonal will always be greater than AE (or other lengths). We need to know the ratio of the sides. Insufficient.
