Answer:

12 inches 20 inches 36 inches

Step-by-step explanation:

ratio of 3:5:9

Multiply each side by x

3x: 5x: 9x

Add the sides together to find the perimeter of 68

3x+5x+9x = 68

Combine like terms

17x = 68

Divide by 17

17x/17 = 68/17

x = 4

The sides lengths are

3*4: 5*4: 9*4

12 : 20: 36
