The perimeter of a regular octagon with side s is 8s. Kiera is making a planter shaped like an octagon to surround the base of her favorite oak tree. Each side of the planter will be 9 inches long. What is the perimeter of the planter? HELP ASAP

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
