would the answer be 6?

Answer 1

Theses riangles are similar. So what is done to 1 to get to 3?

Answer 2

so would it be 6

Answer 3

How 6?

Answer 4

cause red had a vertical leg of one ad went to three and the blue has a vertical leg of three nd if you go up 3 you have 6 I know its probably wrong but that's what I thought

Answer 5

If we do 1+3 that is 4 though. To get from 1 to 3, we multiply 1 by 3, so what wee I to the vertical leg, we also need to do to the horizontal leg.

Answer 6

oh okay so then it would be 9 right

Answer 7

Yep :)

Answer 9
