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 :)


what's the population in 2004? well, from 1994 to 2004 is 10 years later, so t = 10
plug that in, to get P for 2004
A number that is a multiple of both 2 and 5 is 10
= x(8 -8) +(10 +13)
= 0 +23
= 23
Selection D is appropriate.
