Perimeter is adding the sides up..what's 5 + 5 + 8 + 8? @IGOTaFEeling
D or C
Can you add that? @IGOTaFEeling
@IGOTaFEeling , Please participate in the discussion. There are multiple people here willing to help you.
I'm thinking c or d >...
as well
@iGreen gave you the first step
@IGOTaFEeling Yes, that's correct because 5 + 5 + 8 + 8 = 26, and that is the perimeter of ONE rectangle, therefore you can eliminate options A and D, because they state that the first rectangle is not 26.
Now can you add 8 + 8 + 5 + 5 + 5 + 5? It will give you the perimeter of the 2nd rectangle
@IGOTaFEeling Can you add that?
oh yea . one min
8 + 8 + 5 + 5 + 5 + 5=72
@iGreen
No, check again..
36. @iGreen
@iGreen
Okay, which one says 2 rectangles is 36?
C
Yep, so that's your answer.
