Lily decorated a poster with this polygon for school spirit week. What is the perimeter of Lily's polygon?
To find the perimeter of Lily's polygon, we need to add up the lengths of all the sides.
Looking at the polygon, we can see that it has 5 sides. Let's label them A, B, C, D, and E.
Side A has a length of 4 inches.
Side B has a length of 3 inches.
Side C has a length of 4 inches.
Side D has a length of 3 inches.
Side E has a length of 4 inches.
To find the perimeter, we add up the lengths of all the sides:
