    The area of a triangle = 1/2*b*h

    b = 2x
    h = x
    Area = 48

    Can you solve it now?

    In any right triangle with leg of lengths a~\&~b its area is \dfrac{a\cdot b}{2}.
    In your triangle we know that a=2b thus its area is just b^2.
    We also know that c^2=a^2+b^2 where c is the length of the hypotenuse.

    You need to finish it off.
