Find the perimeter of a rectangle with length 8 cm and width 3 cm.

Explanation:
To calculate the perimeter of a rectangle, you use the formula: Perimeter = 2 × (Length + Width) In this case, the length of the rectangle is 8 cm and the width is 3 cm. Plugging these values into the formula, we first add the length and width: 8 cm + 3 cm = 11 cm Next, we multiply the sum by 2: 2 × 11 cm = 22 cm Thus, the perimeter of the rectangle is 22 cm. This is why the correct answer is 22 cm. Understanding this formula and how to apply it is essential for solving perimeter-related problems in geometry, helping to reinforce the relationships among a rectangle's dimensions.
