What is the perimeter of a rectangle with a length of 8 cm and a width of 3 cm?

• A. 20 cm
• B. 22 cm
• C. 24 cm
• D. 26 cm

Answer: (B)

To determine the perimeter of a rectangle, you can 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 gives: Perimeter = 2 × (8 cm + 3 cm) = 2 × 11 cm = 22 cm Therefore, the perimeter of the rectangle is indeed 22 cm. This calculation confirms that the correct answer reflects the proper use of the perimeter formula for a rectangle, taking both the length and width into account.
