We consider the following conversion of units: 10 dm = 1 m 100 cm = 1 m 1000 mm = 1m For this case the lateral area is given by: rectangle 1: A1 = (0.3 * (1/10)) * (6 * (1/100)) A1 = 0.0018 m ^ 2 Rectangle 2: A2 = (0.3 * (1/10)) * (20 * (1/1000)) A2 = 0.0006 m ^ 2 The lateral area is: A = 2 * A1 + 2 * A2 A = 2 * (0.0018) + 2 * (0.0006) A = 0.0048 m ^ 2 Answer: The lateral area of the right is: A = 0.0048 m ^ 2
