Given Information:
- Length of each side of the polygon = 3.9 cm
- Perimeter of the polygon = 31.2 cm
Calculating the number of sides:
- Perimeter of a polygon is the sum of the lengths of all its sides.
- Let the number of sides of the polygon be 'n'.
- Given that each side of the polygon is 3.9 cm, so the perimeter can be calculated as: n * 3.9 = 31.2
- Solving the equation, we get n = 31.2 / 3.9 = 8
Conclusion:
- The polygon has 8 sides, so the correct answer is option 'C' which states that the polygon has 8 sides.
- Length of each side of the polygon = 3.9 cm
- Perimeter of the polygon = 31.2 cm
