You can put this solution on YOUR website! No picture is shown in your question on the site, but one would imagine the sides are folded bent upward at x from the each side, leaving 16-2x for a bottom width for this gutter. You then wish to have the cross section of 16-2x by 1x area be 24 SQUARE inches.
(8-x)x=12
8x-x^2=12
-x^2+8x=12
x^2-8x=-12
