Can u make sure i'm correct and me with the last 3?

1/2 times 10 is 10/2 but it reduces to 5. Last ones are 2/15 and 1/6

7x2=14 2x7=14

5x3=15 3x5=15

6x1/4 = 1/5 1/4x6=1/5

12x2/3=8 2/3x12=8

10x1/2=5 1/2x10=5

2/3x1/5=2/15 1/5x2/3=2/15

1/2x1/3=1/6 1/3x1/2=1/6

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
