    It just involves pythagorean theorem.

    |dw:1337701083545:dw| Here it is. Just put in the formula: c^2 = 2a^2(a = b)(diagonal = c

    d^2=2*s^2 Solve for s then it is s*4

    \[d^2=s^2+s^2\] \[d^2=2s^2\] \[(d^2)/2=s^2\] \[s=d/\sqrt{2} \] P=4*s \[s=4*d/\sqrt{2} \] \[s=2\sqrt{2}*d \]

    1) divide by \(\sqrt{2}\) to get the length of the side then 2) multiply by 4 to get the length of the perimeter
