Now, AREA of rhombus =4*1/2 *4/2 *7/2

A different way to the same result: the diagonal of the rhombus bisects the angles, so we have pairs of 30 angles at each narrow end, and the sum of the interior angles must be (4-2)*180 = 360, and we've already accounted for 4*30 = 120 of that, so that leaves (360-120)/2 = 120 for each pair on the blunt angles, or 60 each.

Yes, the area of a rhombus is given by \(\frac{1}{2}d_1d_2\) so all you need now is the lengths of the two diagonals. Do you know them?

is it 1/2 16*14=112

Looks to me like the half diagonals are 7m and 4m, aren't they? So 14 and 8 would be the full diagonals?
