Answer:

1.36 centimeters

Step-by-step explanation:

Given,

side length ( a ) = 17 mm

To find : Perimeter of regular octagon ( in cm )

Octagon has 8 sides.

Perimeter of regular octagon

= 8 x a

= 8 x 17

= 136 mm

1 mm = 0.1 cm

136 mm

= 136 x 0.1

= 1.36 centimeters ( cm )

Hence,

Perimeter of regular octagon is 1.36 centimeters.
