Answer:258 envelopes
Step-by-step explanation:Total length of the sheet = 3m 24 cm(342 cm)
Total breadth of the sheet=1m 72cm(172cm)
Total area :- 342 cm × 172 cm = 55728
Area that per envelope requires = (l×b)=18 cm ×12cm=216 cm
So, total number of envelope which can be made out of 324 cm by 172 cm sheet of paper = 55728÷216
