If $A$ be the area of a right angled triangle and $b$ be one of the sides containing the right angle, then the length of altitude on the hypotenuse is :

1. $\frac{2Ab}{\sqrt{4b^{4}+A^{2}}}$
2. $\frac{Ab}{\sqrt{b^{4}+4A^{2}}}$
3. $\frac{2Ab}{\sqrt{b^{4}+4A^{2}}}$
4. $\frac{Ab}{\sqrt{4b^{4}+A^{2}}}$
