In a parallelogram ABCD diagonal AC measures 34 m and the perpendicular distance of AC from either of the vertices B and D is 12 m. Find area of parallelogram.
The correct option is B. 408m2
In ΔABC
Base =AC=34 m
Height =BM=12 m
Area of ΔABC=12×34×12
=204 m2
Similarly the area of ΔADC=204 m2 [Diagonal of a parallelogram divides it into two triangles of equal area]
Area of parallelogram =204+204
=408 m2
