The perimeter of the original octagon is:
The perimeter of the new octagon is:
Step-by-step explanation:
When it is mentioned that an octagon is regular, it means that all its sides are equal, therefore, each side of the original octagon has a length of 9 units, considering the formula of the octagon's perimeter:
- Perimeter of an octagon = 8 * length.
By replacing you get:
- Perimeter of the original octagon = 8 * 9 = 72 units.
For the new octagon, it is mentioned that each side increases by 27 units, therefore:
- New length = 27 + 9 = 36 units.
Applying the formula of perimeter of an octagon with the new values we obtain:
- <u>Perimeter of the new octagon = 8 * 36 = 288 units.</u>
