ABCD is a quadrilateral and its diagonals intersect at `O. E,F,G and H` are the midpoints of `AO, BO, CO, and DO` respectively. If the area of `EFGH = 50cm^2`, find the area of ABCD.

ABCD is a parallelogram in which diagonals AC and BD intereset at O. If E, F, G and H are the mid points of AO, DO, CO and BO respectively, then the ratio of the perimeter of the quadrilateral EFGH to the perimeter of parallelogram ABCD is:
