1. The rotation acts with the rule:
Then:
2. The reflection across the y-axis has a rule:

Answer:
3466.64 (≈ 3467) cm²
Step-by-step explanation:
A = 2B + 2 sides and floor
A = 2 * (14 * 24) / 2 + 2 * (45 * √14² + 24²) + 45 * 14
A = 336 + 2500.64 + 630 = 3466.64 (≈ 3467)
Divide 40 by 8 minutes to find the quantity per minute for one machine:
40 / 8 = 5 per minute.
One machine does 5 envelopes per minute.
Now divide 120 by 5 to find the number of machines needed:
120 / 5 = 24
24 machines would be needed.
