Question

The perimeter of a regular polygon is 129.5 cm . if the length of each side is 9.25cm how many sides does the polygon have

​

Answer 1

Given - Perimeter and length of each side

Find - Number of sides

Solution - Perimeter = number of sides*length of each side

Let the number of sides be x. Keep the values in formula to find the number of sides.

129.5 = x*9.25

Shifting 9.25 to other side of equation

x = $\frac{129.5}{9.25}$

Performing division

x = 14

Hence, the polygon has 14 sides.
