Math Problem Statement
The perimeter of a rectangle is 148 feet. The length is 14 feet less than 4 times the width. What are the dimensions of the rectangle?
Solution
We can solve this problem step by step by using the given information and creating equations.
Given:
- The perimeter of the rectangle is 148 feet.
- The length is 14 feet less than 4 times the width.
Let:
- = length of the rectangle
- = width of the rectangle
Step 1: Perimeter formula
The formula for the perimeter of a rectangle is:
Given that , we can set up the equation:
Step 2: Express the length in terms of the width
From the problem, we know that the length is 14 feet less than 4 times the width. So, we can express as:
Step 3: Substitute the expression for into the perimeter equation
Now substitute into the perimeter equation:
Step 4: Simplify the equation
First, expand the terms:
Combine like terms:
Step 5: Solve for
Add 28 to both sides:
Now, divide both sides by 10:
Step 6: Find
Now that we have , substitute it into the expression for :
Final Dimensions:
- Width feet
- Length feet
