The two figures are similar to find the ratios (shaded to non-shaded) of perimeters

perimeter of non-shaded part = 7
perimeter of shaded part = 9
so ratio of shaded to non shaded is =
shaded:non shaded = 9:7 = 9/7
so option b is correct
Answer:
I think it's 9/7 for the nonshaded one and the shaded one is 81/49
Step-by-step explanation: To be honest i'm using both division and multiplication that's really all ad hope I helped you out yo.
