The Pentagon building in Washington, D.C., is shaped like a regular pentagon. If the length of one side of the Pentagon is represented by n + 2, its perimeter would be represented by:
A. 5n + 10
B. 5n + 2
C. n + 10
D. 10n
E. 5n
A regular pentagon has 5 sides of equal length. The perimeter would be 5(n+2) which equals 5n+10.
