What do you mean @IsaiahCC100

hero · Answer

The perimeter of a geometric object is the sum of the lengths of each of its sides:

P = sn

Where s = the length of one side, and n = the number of sides. 

In this case s = 12 and n = 8

So P = ?

Would it be B

hero · Answer

It can't be B because the Perimeter is a "sum".

anonymous · Answer

Oh i am dearly sorry i thought it said to find the length of a side with a 12 perimeter what  you need is one that would be 12 times 8 not divided by 8

Thank you for showing me how i was wrong Hero
