. Find the perimeter of a regular pentagon with each side measuring 4.5 inches.
soldi70 [24.7K]

Answer: 22.5 inches

Step-by-step explanation:

  • a pentagon contains 5 sides

p=s+s+s+s+s

  • note that this is a regular pentagon so it must contain 5 congruent sides
  • each side will be 4.5 inches
