Answer:2(x+1/2x)+3=105
Step-by-step explanation: that is how i got my answer. If not a similar answer i would go with 2x+3=3x+105.
You can automatically eliminate the first answer. The second one has a random 5, so eliminated. and the last one just isn't correct.

The two equivalent equations are d₁= 2a/d₂ and d₂= 2a/d₁ , Option 2 and 5 is the right answer.
<h3>What is a Rhombus ?</h3>
Rhombus is a quadrilateral with all the sides equal to each other.
It is given that d₁ and d₂ are the lengths of the diagonals.
and Area = a
a = (1/2) d₁ * d₂
        d₁ * d₂ = 2a
        It can be written as 
         d₁= 2a/d₂
a = (1/2) d₁ * d₂
         d₂= 2a/d₁
Therefore Option 2 and 5 are the correct answer.
The options of this question are:
1.  d₁=2Ad₂
2. d₁= 2A/d₂
3. d₂= d₁/2A
4. d₁= 2A/d₂
5. d₂= 2A/d₁
