Something is missing here. We would need to know the size of the border (which is maybe what you mean by the width of the frame,)

I am thinking that the border's area would be 600cm and I'm guessing in this problem they're asking for the uniform width around the border.

So the equation that I got was (30-2x)(20-2x) = 600 but I don't know what else to do from there.
