Math Help!!!

Triangle A and triangle B are similar. The perimeter of trianlge A is 15 m and the perimeter of triangle B is 30 m. What is the ration of the perimeter of triangle B to the perimeter of triangle A?
A. 2:1
B. 3:1
C. 3:2
D. 5:3
Is the answer D?

  1. A = 15 m = perimeter of triangle A
    B = 30 m = perimeter of triangle B

    Factors:

    15 = 1, 3, 5, 15
    30 = 1, 2, 3, 10, 15

    15/15 = 1
    30/15 = 2

    Honestly, I would go with A. The perimeter is twice the number of 15 together. So, the perimeter of triangle B is 15 m bigger than the perimeter of triangle A.

    I hope this helps? :)
