If he use a 3 to 1 ratio of beef to pork
1/4 pound

Please clarify the wording of the question more, I do not understand you, but I think the answer is yes

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
