I'm doing math homework...
The Pentagon, in Arlington, Virginia, is one of the world's largest office buildings. It is a regular pentagon, and the length of each of its sides is 921 feet. Fine the area of this pentagon to the nearest thousand feet.
A=1/2ap
p=921X5 which is 4605
a: tan36=460.5 (half of 921) over a
a=460.5/tan36
a=633.8238744
A=1/2X633.8238744X4605
A=1459379.471
A=1459,000 square feet...
I think I did that wrong...but oh well.
Lost me on that...I'm a finance wiz
That other stuff is worthless to me
