Hello!
Every octagon has 8 sides. If each side has a measure of 8cm, you just multiply by 8!
8(8)=64
Therefore, our answer is C) 64 cm
I hope this helps!
The answer is C. 64.
Perimeter is the distance around a figure. If an octagon has 8 sides, all of which are 8 cm, the perimeter can be found by multiplying those two factors.
