First, let’s draw a rectangle.
The problem says that the width of the rectangle is 2.3 cm, and the length is 1.9 cm longer, that is, the length is: 2.3 + 1.9 = 4.2 cm.
Since the perimeter of a rectangle is equal to the sum of all sides, then the perimeter of such a rectangle is: 4.2 + 4.2 + 2.3 + 2.3 = 11 cm.
