The width of the rectangle is 2 cm and the length is 3 times greater. Find the perimeter of the rectangle.

Let’s find the length of the given rectangle.

According to the condition of the problem, the width of this rectangle is 2 cm, and the length of this rectangle is 3 times its width, therefore, the length of this rectangle is:

2 * 3 = 6 cm.

Find the perimeter of this rectangle.

Since the perimeter of any rectangle is equal to the sum of the length and width of this rectangle multiplied by 2, the perimeter P of this rectangle is:

P = 2 * (6 + 2) = 2 * 8 = 16 cm.

Answer: the perimeter of this rectangle is 16 cm.
