Find the value of x in the given equation.
​$$\frac{\sqrt{2401}}{x} = \frac{x}{6.25}$$​​

Correct option is A

Given:
$$\frac{\sqrt{2401}}{x} = \frac{x}{6.25}$$​
Solution:
$$\frac{\sqrt{2401}}{x} = \frac{x}{6.25}$$​
​$$\frac{49}{x} = \frac{x}{6.25} \\x^2 = 306.25 \\x = \sqrt{306.25} \\x = \frac{35}{2} \\x = 17.5$$​​
