Math Problem Statement
Solution
Let's solve the problem step by step.
We are given:
- A square with an area of .
- A rectangle with dimensions and .
- The perimeters of the square and rectangle are the same.
Step 1: Find the side length of the square.
The area of the square is given by: So, to find the side length:
Step 2: Find the perimeter of the square.
The perimeter of a square is times the side length:
Step 3: Write an equation for the perimeter of the rectangle.
The perimeter of a rectangle is given by: For this rectangle, the length is and the width is . So, the perimeter is:
Step 4: Set up the equation.
Since the perimeters of the square and the rectangle are the same:
Step 5: Solve for .
Add to both sides: Divide both sides by :
Final Answer:
The value of is .
