    We can tell you what's wrong in your approach. When the base is changed or doubled then for the triangle to remain a right angled triangle, the hypotenuse must also change accordingly. But the length of hypotenuse is kept constant. Hence the new triangle is not a right angled triangle. So you have to use the Heron's formula.
