Lets find length of other side --> 1/2 * other side * 2 = 2\(\sqrt{3} ==> 2\sqrt{3}\)
Apply Pythagoras to bigger triangle \(2^2 + (2\sqrt{3})^2 = 4 +12 = \sqrt{16} ==> 4\)
So we can calculate the area of triangle again using the altitude ==> \(\frac{1}{2} * 4 * h = 2\sqrt{3} ==>> h =\sqrt{3}\)
Apply Pythagoras to bigger triangle \(2^2 + (2\sqrt{3})^2 = 4 +12 = \sqrt{16} ==> 4\)
So we can calculate the area of triangle again using the altitude ==> \(\frac{1}{2} * 4 * h = 2\sqrt{3} ==>> h =\sqrt{3}\)

Can you please explain it how base is taken as 4??
