  1. In the given figure DE||BC and AD : DB = 5 : 4,
    Then ar(∆DFE)
    ar(∆CFB)


    1. 25
      81
    2. 25
      16
    3. 16
      25
    4. 16
      81
    5. None of these
Correct Option: A

From above given figure , we have
Given :- AD : DB = 5 : 4
ΔADE ∼ ΔAB C( ∴ DE || BC ∴ AA Simillarity)

AD=DE , By property
ABBC

∴
5x
=DE
5x+4xBC

DE=5
BC9

Nowar(∆DEF)=DE2=25
ar(∆CFB)BC281
