Chapter 8, Problem 3PT

To determine

To find: the equation which shows the relationship between the side length and perimeter

Answer to Problem 3PT

The correct option that describe the equation of sequence is B

Explanation of Solution

Given:

Side length (s)	Perimeter (p)
1	5
2	10
3	15
4	20

A $p=5+s$

C $s=5p+5$

B $p=5s$

D $s=5+p$

Calculation:

In the sequence, the terms have common difference of 5.

And. the value of perimeter is five times the side length. It means that the equation of sequence is:

  $p=55$

Conclusion:

Therefore, the correct option that describe the equation of sequence is B
