By definition, all sides of a rhombus have the same length.
Also, the diagonals are perpendicular bisectors of each other.
Because of that, the diagonals divide the rhombus into 4 congruent right triangles.
For each of those triangles, the hypotenuse is a rhombus side, of length ,
and one leg length is .
Applying the Pythagorean theorem we can find the other length, :
.
Solving for ,
Taking one leg as the base and the other leg as the height,
the area of each triangle can be calculated as
,
and the area of the rhombus (4 triangles) is
The length of diagonal BD is approximately
,
or we could say it is approximately .
