Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that <em>each</em> side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

<u>You can set up an equation like this:</u>

4/5 * number of sides = 8

<em>or you can write it in a simpler form as:</em>

4/5x=8

<u>Now solve it like a normal equation:</u>

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.
