Question

each side of a regular polygon is 8.1 length. the perimeter of the polygon is 72.9cm.find the number of sides of the polygon.

Answer 1

Given that length of each side is 8.1 cm

And perimeter of the polygon= 72.9 cm

We know that sum of all sides = Perimeter of the polygon

Let the number of sides be x

x * 8.1 = 72.9
⇒ x = 72.9 / 8.1
⇒ x = 9

Thus there are 9 sides
