### Instruction: A regular polygon has perimeter 108 cm and each side has length 12 cm.  How many sides does this polygon have?### Response: A regular polygon is a polygon with equal sides and angles.
If each side is 12 cm, then I can divide the perimeter by 12 to get the number of sides.
So 108 divided by 12 is 9.
This means the polygon has 9 sides.
I can check my answer by multiplying 9 by 12 and seeing if I get 108.
Yes, 9 times 12 is 108, so I'm confident that 9 is the correct answer.
