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
