Answer:
The perimeter of a rectangle is:
Step-by-step explanation:
Given
The width of a rectangle w = 8n - 8.5 feet
The length of a rectangle l = 8.5n + 10 feet
To determine
The perimeter of a rectangle = P = ?
The perimeter of a rectangle can be determined using the formula
[tex]P = 2(l+w)[/tex]
substitute l = 8.5n + 10 and w = 8n - 8.5
[tex]P=2\left(8.5n+10+8n-8.5\right)[/tex]
[tex]=2\left(16.5n+10-8.5\right)[/tex]
[tex]=2\left(16.5n+1.5\right)[/tex]
[tex]=33n+3[/tex]
Therefore, the perimeter of a rectangle is:
