all sides of a rhombus are equal in length.
the diagonals of the rhombus intersect at a degree angle.
the diagonals and the sides of the rhombus form four right triangles whose sides are:
one leg of these right triangles is equal to the length of the one diagonal
the other leg of these right triangles is equal to the length of the other diagonal
the hypothenuse is equal to the length of the side we are looking for
so, if side is , use Pythagoras theorem to find it using the length of the legs
one leg is long and the other leg is long
then

9/2 = 4.5
6^2 = 36
4.5^2 = 20.25
36+20.25= 56.25
sqrt 56.25 = 7.5 is the length of each of two opposing parallel sides.
