. Then equate them to find the answer.
The correct answer is:
In this question we are given 
,
and we have to find the value of 
Step1: Using the property of Right angle triangle
It is given that , therefore side 
is the hypotenuse and Sides 
are base and height
We know that area of a right angle triangle is
Step2: Using Heron Formula
By squaring both sides we get,
