Answer:
[tex]2(4n+3)[/tex]
[tex]8n+6[/tex]
Step-by-step explanation:
We are given that
Let n represent the width of pool
Length of pool=[tex]3n+3[/tex]
We have to find two expression which represent the perimeter of the pool.
We know that
Perimeter of rectangle=[tex]2(l+b)[/tex]
Where l=Length of rectangle
b=Width of rectangle
Using the formula
Perimeter of pool=[tex]2(n+3n+3)[/tex]
Perimeter of pool=[tex]2(4n+3)[/tex]
Perimeter of pool=[tex]8n+6[/tex]
Hence, two expressions that represent the perimeter of the pool is given by
[tex]2(4n+3)[/tex]
[tex]8n+6[/tex]
