Unfortunately they're annotated in my native language, but it may be useful for whoever likes to solve this kind of stuff. Good luck with your newlyfound group BTW.

 i think the answer is 45

Is it 35?

Is't 32

1) 8+4+1=13 the perfect square nearest to 13 is 16 ... 13+16=29

2) 2+3+4=9  the perfect square nearest to 9 is 9 ... 9+9=18

3) 1+6+9=16 the perfect square nearest to is 16.... 16+16=32

45?

32! What does this have to do with chess though?

Accually there is only one of you find the correct answer?

who nominate himself?

52 works mathematically as a relation but you said it was wrong oh well ill explain it anyway if you subtract the perimeter triangles from the center you will get the second highest value squared

8,4,1--->29   29x29=841

3,2,4--->18    18x18=324

1,9,6--->?     ?x?=196 thus ?=14

14 it is then :-)

lol , that's right !!

The problem with this problem is that there's more than 1 answer, depending on how you solve it. Everyone, as long as they had a reason that was without mistake, should be correct.
