What is the perimeter of a rectangle with a length of 8 cm and a width of 5 cm?

  1. 26 cm

  2. 30 cm

  3. 40 cm

  4. 50 cm

The correct answer is: 26 cm

To find 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 5 cm. First, add the length and the width together: 8 cm + 5 cm = 13 cm. Next, multiply this sum by 2 to find the perimeter: 2 × 13 cm = 26 cm. Therefore, the perimeter of the rectangle is 26 cm, which corresponds to the correct answer. This method ensures that the perimeter accurately reflects the distance around the rectangle.
