my question is , let be x and y the sides of a rectangle, or let be 'r' and h the radius and height of a cilinder, if we imposed the condition that the commutators

[x,y] and [r,h] are different from 0 then

could we 'draw' a rectangle or a cilinder or would we have a similar 'Uncertainty principle' similar to Heisenberg's that would avoid measuring the Areas of rectangles and cilinders?

another question, if x and y do not commute , how can you define

\iint_{D} f(x,y)dxdy ?? where 'D' would be a curve that depends on x and y
