Question

AD is the median of triangle ABC , ar(triangle ABC) = 20cm2 . find ar(triangle ABC)
.....
this is the right question
please tell me the answer​

Answer 1

Answer:

Please look at the figure provided.

If we look at triangle ABD and triangle ACD

They have equal bases BD and CD                (AB=CD because AD is median)

Also they lie between same parallels so they have equal area

Thus ar(ABD) + ar(ACD) = 20

So ar(ABD) = ar(ACD) = 20/2 = 10cm2

Hope it helps. Please mark as brainliest :)

P.S. There is probably a mistake in question because you have asked area of triangle abc when it is already given but I hope this is what you want
