You can put this solution on YOUR website!
Drawing a picture would help greatly in analyzing this.

u, the uniform width for the top and sides;
2u, the uniform width at the bottom.

The printed area will be %2826-2u%29%2831-u-2u%29=440;
you would transcribe that equation from the drawing.

Can you handle the rest of the arithmetic and solve for u?
