What is the perimeter of a rectangle with a length of 5 cm and a width of 3 cm?

Explanation:
To find the perimeter of a rectangle, you use the formula: Perimeter = 2(length + width) In this case, the length of the rectangle is 5 cm and the width is 3 cm. First, you need to add the length and width together: 5 cm + 3 cm = 8 cm. Next, multiply this sum by 2 to find the perimeter: 2 × 8 cm = 16 cm. Thus, the perimeter of the rectangle is 16 cm. This matches the first choice, confirming that it is the correct answer. The other choices do not reflect the correct calculation of the perimeter using the given dimensions, emphasizing the importance of accurately applying the formula for any rectangle's perimeter.
