Question

A hotel manager is adding a tile border around the​ hotel's rectangular pool. let n represent the width of the​ pool, in feet. the length is 3 more than 3 times the​ width, as shown. Write two expressions that represent the perimeter of the pool.

Answer 1

Answer:

$2(4n+3)$

$8n+6$

Step-by-step explanation:

We are given that

Let n represent the width of pool

Length of pool=$3n+3$

We have to find two expression which represent the perimeter of the pool.

We know that

Perimeter of rectangle=$2(l+b)$

Where l=Length of rectangle

b=Width of rectangle

Using the formula

Perimeter of pool=$2(n+3n+3)$

Perimeter of pool=$2(4n+3)$

Perimeter of pool=$8n+6$

Hence,  two expressions that represent the perimeter of the pool is given by

$2(4n+3)$

$8n+6$
