Answer :

Given that,

Area of parallelogram ABCD = 124 cm2


Construction: Draw AP perpendicular to DC


Proof: Area of parallelogram AFED = DF * AP (i)


Area of parallelogram EBCF = FC * AP (ii)


And,


DF = FC (iii) (F is the mid-point of DC)


Compare (i), (ii) and (iii), we get


Area of parallelogram AEFD = Area of parallelogram EBCF


Therefore,


Area of parallelogram AEFD =


= = 62 cm2
