Let x=length of first side.

Since "one side is twice as long as the first", this means that

Also, because "another is half as long as the first side", this means that

However, there's a problem. In order for any triangle to be constructed, the lengths of any two sides must be greater than the length of the third side. So for instance, this means that .

Plug in and

Add

Since this inequality is never true for any positive x values, this means that you cannot construct a triangle with sides of x, 2x, and (go ahead and try it out on paper if you don't believe me).

So I would double check the problem.
