This is contentious issue.

two rectangles with dimensions 4x2 and 2x4.
are these two different rectangles?

If we go with our high-school funda, length>breadth --> both are same.
If we plot them, both have different values for x and y. --> both are different.

CAT me kya karna hai?? @scrabbler

which one is greater between

(1) between 232/322 and 233/332
(2) between (0.2)^-1/3 and (0.3)^-1/2

please explain your method too.
