Each side of the Pentagon Building in Washington DC is 900 feet long. What is the perimeter ?
Vika [28.1K]
The perimeter of a Pentagon is all the length of the sides added up
A pentagon is a five sided shape
so...
900+900+900+900+900
or 900*5
That is 4500.

The perimeter of the Pentagon Building in Washington DC, whose side is 900 feet long, is 4500 feet around.

Hope this helps :)
