Question

In ABC AD is a medium if ar (ADB) = 53 cm^2 then find ar (ABC)​

Answer 1

Answer:

divides the triangle into two triangles of equal area.

BE is the median of triangle △ABD

∴ar(△ABD)=2ar(△ABE)

⇒ar(△ABD)=2×15=30 cm

2

Now, AD is the median of triangle ABC

∴ar(△ABC)=2ar(△ABD)

⇒ar(△ABC)=2×30=60 cm square2
