Answer :
Given that,
Area (
= 12 cm2
D is the mid-point of BC
So,
AD is the median of triangle ABC,
Area (
= Area (
= 
* Area (
Area (
= Area (
= 
* 12
= 6 cm2 (i)
We know that,
Area of triangle between the same parallel and on the same base
Area (
= Area (
Area (
+ Area (
= Area (
+ Area (
Area (
= Area (
(ii)
ME is the median of triangle ADC,
Area (
= Area (
+ Area (
Area (
= Area (
+ Area (
[From (ii)]
Area (
= Area (
6 cm2 = Area (
[From (i)]
Hence,
Area (
is 6 cm2.
