Math Problem Statement
Solution
Let's solve this problem step by step.
Problem Recap:
- Length of the rectangle = 5 cm longer than twice its width.
- Perimeter of the rectangle = 88 cm.
We need to find the width of the rectangle.
Step 1: Define variables.
- Let the width of the rectangle be (in cm).
- Then, the length of the rectangle will be cm (since it's 5 cm longer than twice the width).
Step 2: Use the perimeter formula for a rectangle.
The perimeter of a rectangle is given by:
Substitute the given perimeter (88 cm) and the expressions for length and width:
Step 3: Simplify and solve for .
First, expand the equation:
Now, subtract 10 from both sides:
Finally, divide both sides by 6:
Conclusion:
The width of the rectangle is 13 cm.
