January 30, 2021 | education
| 1. Recall the formula by which you can determine the perimeter of a rectangle:
P = 2 * (a + b), where a and b are the sides of the rectangle.
2. We know the width (2.3 cm), find out its length:
2.3 + 1.9 = 4.2 cm.
3. Define the perimeter of the rectangle:
P = 2 * (2.3 + 4.2) = 2 * 6.5 = 13 cm.
Answer: The perimeter of the rectangle is 13 cm.
