Remmeber that an octagon is a polygon formed by chain of 8 straight line segments.

The first valid name for a polygon of eight sides is octagon (from greek oktagonon, which means eight angles)

The second valid name for a polygon of eight sides is eight-sided polygon.

The third valid name of a polygon of eight sides is 8-gon. After 6 sides, mathematicians usually refer to these polygons as n-gons, so an eight-sided polygon will be an 8-gon.

We can conclude that the three valid names for an octagon are: octagon, eight-sided polygon, and 8-gon.

Answer:

I believe the answer would be 1,706.1

Step-by-step explanation:

Since the problem is a fraction, it would be easier to covert it to a decimal. This is made simple since the fraction is out of ten. Now, the number should look like this: 36.3

Now let's do long division.

Now we have answer of 1706.1

We have one more step. Since there is one number behind the decimal point in 36.3, we have to put one number behind the decimal point in our answer.

As you can see in the last picture, we have 1,706.1.

I hope you understand after I have explained. If you have any other troubles, tell me.
