Plz and show me how you got your answer

It's real simple, 

Total of words typed= 242
How long it took her to type those words= 6 minutes

When they say "unit rate" they are trying to confuse you. It just means how many words she type per minute.
So take 242 and divide it by 6

242/6= around 40

So the "unit rate" is 40.

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
