Call the length of the wire, x.
For the square, each side is x/4. Thus its area is x%5E2%2F16.
For the equilateral triangle, each side is x/3. And its area is

If we divide the area of the triangle by the area of the square, we get
%28%28x%5E2%29%2A%28sqrt%283%29%2F36%29%29%2F%28x%5E2%2F16%29
The x^2 cancels and leaves us the answer...
4%2Asqrt%283%29%2F9
