Ad is median so it divides trianle into parts having equal area
so... area of trianle ABC =2area of triangleABD
now E is mid point so.. BE is median of trainle ABD
so..area of ABD =2area of trianle BED
ABD=2*10=20
area of ABC=2ABD
2*20=40
so... area of trianle ABC =2area of triangleABD
now E is mid point so.. BE is median of trainle ABD
so..area of ABD =2area of trianle BED
ABD=2*10=20
area of ABC=2ABD
2*20=40
