3 0

If a polygon is regular, it has congruent sides and congruent angles. We know that an octagon has 8 sides and a perimeter of 80cm. Because the sides of the octagon are congruent, we can divide 80 by 8 to get 10 centimeters for one side. Hope this helps!! :)

You would use unit rate for this. If Austin makes $209 in 11 hours, then he makes 209/11 = 19 dollars in 1 hour.

Then, we can make a proportion:

$19/1 hour = $152/ x hours

Cross multiply:

152 = 19x

Solve for x to get:

x = 8 hours.
