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 :)

Zinaida [17]

9 laps.

Step-by-step explanation:

-Let x be the number of laps Taylor runs.

-Given that the ratio of Kyle to Taylor laps is 2:3, we express the actual laps in meters to solve for x as follows:

$\frac{Kyle}{Taylor}=\frac{2}{3}\\\\\therefore \frac{2}{3}=\frac{6}{x}\\\\2x=18\\\\x=9$

Hence, Taylor runs 9 laps.
