Question

The sides of ABC are 30 units, 40 units, and 60 units in length. If the corresponding sides of XYZ are r times as long as the sides of ABC, which expression gives the perimeter of XYZ?

Answer 1

130r







3 x 130r

Answer 2

130/r

Answer 3

3 x 130r/2

Answer 4

130r/3

Answer 5

I think it would be 3 x 130r I'm not 100% sure though. Let me check.

Answer 6

ok , thanks!(:

Answer 7

@SolomonZelman ? (:

Answer 8

Yes, it would! Because you would have to do 130r to get whatever, then multiply it by 3 to get the perimeter of XYZ. :)
