Answer 1

Answer:

Step-by-step explanation:

E is mid-point

CE = 1/2 CA

but BD = CE

and BD ll CA, so BD ll CE

BDEC is parallelogram

ar(BDC) = ar(EBC) [triangles between same lls and on same base have equal area]

BE is median of ABC,

ar(EBC) = 1/2 ar(ABC)

THUS, ar(BDC) = 1/2 ar(ABC)

finally, 2ar(BDC) = ar(ABC)
