The triangle is a right angled isoceles triangle.

We know that for a right angle triangle,
 c^{2}  =  a^{2}  +  b^{2}
where c is the hypotenuse, a and b are the sides

we know that this is an isosceles triangle,
which means that
a = b
So,
[tex] c^{2} = a^{2} + a^{2} [/tex]

or, c = a  \sqrt{2}

Now, dump these values in heron's formula for area of a triangle
You will get the values of a,b,c
Either a or b will be the longest altitude of the triangle
