Solution
The correct option is D18ar(ΔABC) In ABC, it is given that D is the midpoint of BC, E is the midpoint of BD and O is the midpoint of AE. Then BE=14BC OR OE=12AE WE know thet area of triangle =12h.b Area of triangle ABC=12BC(AE) Area of triangle BOE=12BE(OE) Then area of triangleBOE=18area of triangleABC
