Question

The perimeter of a regular octagon, with each side measuring 15 cm will be:

• A. (15 x 8) cm
• B. 15 cm + 15 cm + 15 cm +.......... 8 times
• C. 120 cm
• D. All the above

Answer 1

The correct option is C

120 cm

Given, length of the side of the octagon = 15 cm
Perimeter = sum of all sides
Since it is a regular octagon, so the figure will have 8 sides and all sides will be equal.
$\therefore$ Perimeter = 8 x length of a side
= 8 x 15 cm
= 120 cm
