tan∠EFA = 30 / 18

 

DG = tan∠EFA  * DF

 

[DGF] = 30 cm2

or

18 / 30 = 6 / DG

 

DG = 10

 

[DGF] = 1/2(10 * 6)

I disagree as AB is 30cm and not DG

Even if DG was 30, that's not the way to find the area of a triangle!

So DGF can't be 30 square.

Yes I agree with IhaveOBJD, there's no possible way for DGF to be 30, 30 = AB or BC or CD or AD, not DGF area.

We were talking to a guest answerer who said it was the answer was 900 or 30^2. Apparently, they removed it.
