Find all such pairs of positive integers ,
for which a rectangle with dimensions can be built
from pieces created from 6 squares as shown.
(Note that you can both rotate and flip the pieces):
OK, so we know that we can create a 3x4 rectangle
. . by simply putting together this shape and the one rotated by
We can also create rectangles for positive integers and
But what else? .I'm kind of clueless ...
Me too . . .
I've tried to find other possible rectangles, but have failed so far.
