Finding the Sides of a Rectangle Given Its Perimeter and Area

To find the sides of a rectangle when the perimeter is 20 cm and the area is 24 cm², we can use the following steps:

1. Understand the Formulas: - The perimeter of a rectangle is given by the formula: \(2 \times (length + width)\). - The area of a rectangle is given by the formula: \(length \times width\).

2. Use the Given Information: - We know that the perimeter of the rectangle is 20 cm and the area is 24 cm².

3. Solve for the Sides: - Let's denote the length of the rectangle as \(l\) and the width as \(w\). - We have the following equations: - \(2 \times (l + w) = 20\) (perimeter equation) - \(l \times w = 24\) (area equation)

4. Solving the Equations: - We can solve the perimeter equation for one of the variables and then substitute it into
