## Answers ( )

Answer:Cell A = 72

Cell B = 96

Step-by-step explanation:A regular octagon has 8 sides that are if equal length. Perimeter of any given octagon with side length, s, can be calculated using this equation that shows the relationship between its side lenght (s) and perimeter (P):

To complete the table, simply plug in the value of a in each case.

For Cell A, when s = 9,

For Cell A, when s = 12,

Answer: A:72,96 B: She Will Need 160 Inches Of Wire.Step-by-step explanation: 20×8=160
