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.
