Question

Each side of a regular polygon is 5.25 cm in length. The perimeter of the polygon is 36.75 cm. How many sides does the polygon have? If an equilateral triangle had the same perimeter, what would be the length of each side?

Answer 1

36.75/5.25= 7
so there are 7 sides of that polygon 

Answer 2

It has 7 sides.
if it was an equilateral triangle, the length of each side would be 12.25
