Calculation of 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 length of the rectangle is given as 12 cm, and the width is one-third of the length.

Let's calculate the perimeter using the given information.

Step 1: Determine the width of the rectangle. The width is one-third of the length, which means it is 12 cm divided by 3. Width = 12 cm / 3 = 4 cm.

Step 2: Calculate the perimeter of the rectangle. The perimeter of a rectangle is given by the formula: P = 2 * (length + width).

Substituting the values: P = 2 * (12 cm + 4 cm) = 2 * 16 cm = 32 cm.

Therefore, the perimeter of the rectangle is 32 cm.
