What was the experimental probability of how many times an even number was actually rolled using the table?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2
