  • Width of the pool is represented by pp feet.
  • Length of the pool is 1 more than 4 times the width, so the length is expressed as 4p+14p + 1.
  • You are asked to find two expressions that represent the perimeter of the pool, with several options provided for selection.

Understanding the Formula:

The formula for the perimeter PP of a rectangle is given by:

P=2×(length)+2×(width)P = 2 \times (\text{length}) + 2 \times (\text{width})

Using the given expressions:

  • Length = 4p+14p + 1
  • Width = pp

Thus, the perimeter PP can be written as:

P=2×(4p+1)+2×pP = 2 \times (4p + 1) + 2 \times p

Simplifying:

P=2(4p+1)+2p=8p+2+2p=10p+2P = 2(4p + 1) + 2p = 8p + 2 + 2p = 10p + 2

Now, let's review the provided options:

  1. 10p+110p + 1
  2. 5p+15p + 1
  3. 26p+126p + 1
  4. 4(p+4p+1)4(p + 4p + 1)
  5. 10p+210p + 2
  6. 2p+4p+12p + 4p + 1

Correct Expressions:

From the calculation above, the correct expression for the perimeter is 10p+210p + 2. Therefore, the correct option is:

  • E. 10p+210p + 2

This matches the formula for the perimeter based on the provided dimensions of the pool.

Would you like more detailed steps, or do you have any questions about this? Here are some follow-up questions:

  1. How would the perimeter change if the width was doubled?
  2. What is the formula for the area of the pool?
  3. How can we find the perimeter if the length and width are given in numerical values?
  4. If a second border of tiles is added, how would the perimeter change?
  5. How does the relationship between the length and width affect the perimeter formula?

Tip: When dealing with geometry problems involving perimeter, always check if the dimensions are given in terms of a variable, and apply the perimeter formula accordingly.
