b: If Gabby wants to make an octagon with a side length of 20 inches using wire, how much wire does she need? Justify your reasoning with an explanation of whether perimeter is proportional to the side length. (3 points)

Answer 1

Answer: A:72,96 B: She Will Need 160 Inches Of Wire.

Step-by-step explanation: 20x8=160

Answer 2

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,
