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 (42)*180 = 360, and we've already accounted for 4*30 = 120 of that, so that leaves (360120)/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?

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