Answer: 22.5 inches
Step-by-step explanation:
- the general formula for finding perimeter is [tex]p=s+s+s...[/tex]
- a pentagon contains 5 sides
[tex]p=s+s+s+s+s[/tex]
- note that this is a regular pentagon so it must contain 5 congruent sides
- each side will be 4.5 inches
- the formula can be changed to [tex]5(s)[/tex] and solved:
[tex]5(4.5 in)=p[/tex]
∴ 22.5 inches = perimeter of the pentagon
