Finding the Perimeter of a Rectangle

To find the perimeter of a rectangle, we need to know the length and width of the rectangle. In this case, the width of the rectangle is given as 3 cm, and the length is three times the width.

Let's calculate the perimeter step by step:

1. Find the length of the rectangle: - The width is given as 3 cm. - The length is three times the width, so the length is 3 * 3 = 9 cm. (Source

2. Calculate the perimeter: - The perimeter of a rectangle is given by the formula: perimeter = 2 * (length + width). - Substituting the values we found, the perimeter of the rectangle is 2 * (9 cm + 3 cm) = 2 * 12 cm = 24 cm. (Source

Therefore, the perimeter of the rectangle is 24 cm.
