Which has the largest perimeter, Polygon A or Polygon B? Polygon A is a square (5 cm each side) - Polygon B is 20 sided (1 cm each side).
P = the sum of the sides
Polygon A = 4 * 5 = 20
Polygon B = 20 * 1 = 20
To determine which polygon has the largest perimeter, we need to calculate the perimeter of each polygon and compare them.
To find the perimeter of a square (Polygon A), we multiply the length of one side by 4, since all sides of a square are equal. The length of each side of Polygon A is given as 5 cm, so the perimeter of Polygon A is:
Perimeter of Polygon A = 4 * 5 cm = 20 cm
For Polygon B, which is a 20-sided polygon with sides of 1 cm each, we need to multiply the length of one side by the number of sides (20) to find the perimeter. The length of each side of Polygon B is given as 1 cm, so the perimeter of Polygon B is:
Perimeter of Polygon B = 1 cm * 20 = 20 cm
Comparing the perimeters, we see that both Polygon A and Polygon B have a perimeter of 20 cm. Therefore, both polygons have the same perimeter.
