Answer:
C. 105 
Step-by-step explanation:
<em><u>The formula for a regular polygon is:</u></em>
<em><u /></em>
→ p is the perimeter and a is the apothem

80÷12= 6 2/3
12×12×12×12×12×12=72
so 12 goes into 80 evenly 6 times, but there is a remainder so you have to include it
80-72=8
so that leaves you with 8/12 which is 2/3 when simplified
now you have 6 + 2/3 = 6 2/3
