Find two rectangles, with integral sides, such that the area of the first is three times the area of the second, and the perimeter of the second is three times the perimeter of the first.

Nice.
Curious about your algorithm.
Mine ran forever with n=100, (and came up empty.)

I tried direct solutions also, restricting the first to be square and the second to be 1xm.
Came up empty again.
