Step-by-step explanation: The perimeter is the distance around the shape. As you can see there are 6 sides. that means that 6 sides share 54 centimeters so if you wanted to find the perimeter for one side (which is what y is representing) then you would divide 54 by 6 which gives you 9. To check you can even multiply the perimeter for one side (9) by the total sides (6) which gives you 54. So your answer would be 9
