Solution

The correct option is C

60 cm2


FE is the median of ABF...... (given)

Area of Δ ABF=2×Δ AFE ..... (median divides a triangle into two triangles of equal area) Δ ABF=30 cm2

Area of parallelogram ABCD=2×Δ ABF…… (area of parallelogram is twice the area of triangle,if both are on the same base and between the same parallels)

Area of parallelogram ABCD =2×30=60 cm2

Hence (C)
