Answer:
5 feet long and 1 foot wide, and vise versa.
Explanation:
First of all, we can make pairs.
Then just look at what I do
(6, 0) <= This can't be possible
(5, 1) <= This is the largest
(4, 2) <= This isn't the largest
(3, 3) <= This isn't the largest
(2, 4) <= This isn't the largest
(1, 5) <= This is the largest
(0, 6) <= This can't be possible
The ones labled "This is the largest" are the correct ones
