Answer :


AD is the median, D is the mid-point of B and C.


Co-ordinates of D = =


Area of triangle (x1 (y2 – y3) + x2 (y3 – y1) + x3 (y1 – y2))


Area of ΔABD =


= = -3 sq. units


= 3 sq. units [ Area cannot be negative]


Area of ΔADC =


= = -3 sq. units


= 3 sq. units [ Area cannot be negative]


ar (ΔABD) = ar (ΔADC) = 3 sq. units


The median divides the triangle into two equal areas.
