Therefore, DCE angle = BEC angle.
Angle CDB= angle DBE
Therefore, triangle DFC is equal to triangle EBF.
The DC ratio EB is equal to 1 ratio 2.
So, s triangle DFC=4S triangle BFE.
And s triangle DCB= 1/2*72=32cm2.
That is, s triangle DFC+S triangle ECB=32cm2.
Similarly, s triangle EFB+S triangle BCF= 18cm2.
And s triangle DFC=4S triangle EFB.
So 4S triangle EFB+S triangle BCF=36cm2.
So the 3S triangle EFB= 18cm2.
S triangle EFB=6cm2
