A side of regular polygon is 3.5 cm in length.the perimeter of the polygon is 17.5 cm. How many sides does the polygon have?
17.5/3.5 = 5
how the
17.5 รท 3.5 = 5
To find the number of sides of a regular polygon, we can use the formula:
n = P / S
where:
n = number of sides
P = perimeter of the polygon
S = length of each side
In this case, we are given that the length of each side (S) is 3.5 cm and the perimeter of the polygon (P) is 17.5 cm. Plugging these values into the formula, we can find the number of sides:
n = 17.5 cm / 3.5 cm
n = 5
Therefore, the polygon has 5 sides.
