The two equivalent equations are dâ= 2a/dâ and dâ= 2a/dâ , Option 2 and 5 is the right answer.
Rhombus is a quadrilateral with all the sides equal to each other.
It is given that dâ and dâ are the lengths of the diagonals.
and Area = a
a = (1/2) dâ * dâ
    dâ * dâ = 2a
    It can be written as
    dâ= 2a/dâ
a = (1/2) dâ * dâ
    dâ= 2a/dâ
Therefore Option 2 and 5 are the correct answer.
The options of this question are:
1. Â dâ=2Adâ
2. dâ= 2A/dâ
3. dâ= dâ/2A
4. dâ= 2A/dâ
5. dâ= 2A/dâ
