Can you find out the area of one such triangle?
OpenStudy (mythorius):
oh. p is peremiter.. should have known
OpenStudy (faiqraees):
P is the perimeter of one pentagon right?
OpenStudy (mythorius):
I don't know if it means perimeter for the side or the top.

It cant be for the side

Im going to guess so
So if that's the case then it equals 172.05
OpenStudy (mythorius):
the area of the pentagon=172.05
OpenStudy (faiqraees):
No the area of pentagon has to be in terms on K
