Question

The three s ides of $triangle A B C$ are extended as shown so that $B D equals fraction numerator 1 over denominator 2 end fraction A B comma C E equals fraction numerator 1 over denominator 2 end fraction B C$ and $A F equals fraction numerator 1 over denominator 2 end fraction C A$ Find the ratio of the area of $capital delta D E F$ to that of $triangle A B C.$

14 : 5
10 : 3
13 : 4
