Question 430227: The ratios of the perimeters of two similar triangles is 1:3. If the length of a side of the smaller triangle is 3, the length of the corresponding side of the larger triangle is
a. 1
b. radical 3
c. 3 radical 3
d. 9

So far, the work i have is:
1/3=3/x
x=9?

The ratios of the perimeters of two similar triangles is 1:3. If the length of a side of the smaller triangle is 3, the length of the corresponding side of the larger triangle is
larger/smaller = larger/smaller
------
Proportion:
x/3 = 3/1
x = 9
