Find the length of the given rectangle.
According to the condition of the problem, the width of this rectangle is 1.9 cm, and the length of this rectangle is twice the width, therefore, the length of this rectangle is:
1.9 * 2 = 3.8 cm.
Find the perimeter of this rectangle.
Since the perimeter of the rectangle is equal to twice the sum of the length and width of the rectangle, the perimeter of this rectangle is:
2 * (1.9 + 3.8) = 2 * 5.7 = 11.4 cm.
Answer: 11.4 cm.
