I need help please and thank you

The parameter of a 2-D figure is the total length of its boundaries.

Step-by-step explanation:

In the given figure a hexagon is given with the length of its sides given in mixed fraction.

A mixed fraction can be solved by    

So adding the given sides in the figure:

The perimeter of the given figure is 71.75

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.

hope this : )

your question is incomplete, write all the numbers in the sequence that it tells you.
