number feared by pathagoreans?

i think this question has been asked before but it would be really great if you could help. its the number feared by pathagoreans, since it lies halfway between the only two intergers that can be both the perimeter and the area of the same rectangle.

i have no idea whatsoever.dunno

Good start ... ab = 2(a+b) ... 3x6 = 2(3+6) = 18

I guess 0 doesn't qualify? It is an integer ...

The other is a rectangle with all 4 sides = 4 for an area and perimeter of 16.  So the feared number is 17 which is halfway between 16 and 18.

Re: number feared by pathagoreans?

Maybe it was an "irrational" fear.
