If a rectangle has a length of 8 cm and a width of 3 cm, what is its perimeter?

Explanation:
To find the perimeter of a rectangle, you use the formula: Perimeter = 2 × (length + width). In this case, the rectangle has a length of 8 cm and a width of 3 cm. By substituting these values into the formula, you calculate: Perimeter = 2 × (8 cm + 3 cm) = 2 × (11 cm) = 22 cm. Thus, the perimeter of the rectangle is 22 cm. This confirms that the first choice is indeed the correct answer to the question.
