Answer:

a² = 36

Explanation:

We are given the equation
(a)/(4) = (9)/(a)

Here, we have to simplify the equation as given in options.

Now,


(a)/(4) = (9)/(a)

Multiplying both sides with 4a, we get


(a)/(4) * (4a) = (9)/(a) * (4a)

Cancelling 4 in the left hand side and cancelling a in the right hand side we get,

⇒ a × a = 9 × 4

a² = 36

Therefore, the first option is correct. (Answer)
