GRE GEOMETRYThe Answer to me looks like 'D' because two cases are possible using Triplets AB = 5 Always ( stated)
Coming to AF and BF when
CASE 1 ---- AF = 3, BF = 4 ( Triplet) continuing ... we can see that FE = 7 (since AD = 13)
CASE 2----- AF = 4 , BF = 3( Triplet ) continuing ... we can see that FE = 5 (since AD = 13)
from CASE 1 = BF(=4)*FE(=7) ( Area BCEF) = 28
from CASE 2 = BF(=3)*FE(=5)( Area BCEF) = 15
Please let me know if made any Mistake
