Not sure on this one can someone plz

So what you do is u ask your self how many time can 3 go into 11 without passing 11. it goes it 3 times without passing 11 ,so you have 3 wholes .and the 2 extras are 2 thirds so your answer is 3 and 2 thirds.

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
