I didn't do the square one but for the triangles all but one involved no trial and error and the last one is simple once you get : a+b =a+c+2; b=c+2; c+b = 20; so c+b/2 =10; 2/2 = 1 so they can only be 9 an 11 solving for a = 12 is almost trivial

That leaves 4 boxes unknown. They can probably be solved with a system of 4 equations and 4 unknowns. Regards Matt
