How can you rename 5,400 as hundreds

The answer is 54 hundreds because if you divide by 100 it's 54.

Five thousand and four hundreds.
hope i helped

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

Hope i can you!
