ABCD is a parallelogram. The diagonals AC and BD intersect at the point O. If E,F,GandH are the mid-points of AO,DO,COandBO respectively, then the ratio of (EF+FG+GH+HE) to (AD+DC+CB+BA) is:
In the figure, ABCD is a trapezium. E and F are mid points of diagonals AC and BD respectively. Then, \(\frac{EF}{AB - DC}=\)
