Hello!

The length and width are given.

We know the formula for calculating perimeter :

\fbox {Perimeter = 2(Length + Width)}

Let's solve!

  • Perimeter = 2(123 + 17k + 24k - 49)
  • Perimeter = 2(41k + 74)
  • \fbox {Perimeter = 82k + 148}

∴ The perimeter is 82k + 148.

Lulu wants to get fit. She started with 50 laps a day and she intends to add 10 laps every week. Write a mathematical expression
Bumek [7]

The mathematical expression for the given statement is 50 + 10x

<h3>How to write a mathematical expression for this statement?</h3>

The given parameters are:

Initial distance = 50 laps

Rate of increment = 10 laps each week

Represent the number of weeks with x

So, we have:

Number of laps = Initial distance + Rate of increment * Number of weeks

This gives

Number of laps = 50 + 10 * x

Evaluate

Number of laps = 50 + 10x

Hence, the mathematical expression for the given statement is 50 + 10x
