Given a triangle whose three sides are integer values, and the area of which is divisible by 20, find the smallest possible side for which these  conditions hold true:
 
  •   two sides are odd numbers
  •   at least one side is a prime number.

Should we find a triangle, that meets the conditions, that has a side that is smaller then the smallest side of any other triangle that meets the conditions?

ah i see where i made my mistake.

i assumed height is always (1/2 base)^2 - other side^2

which isn't necessarily so.

(only true for isosceles triangles or equilateral.)

yes, when you phrase it that way, i see how complex it sounds.  Ahh the joys of the English language.  Seems much more clear in my native language  ^_^
