Question

5. How many envelopes can be made out of a sheet of paper 3 m 24 cm by 1 m 72 em. If each
envelope requires a piece of paper of size 18 cm by 12 cm?​

Answer 1

Answer:

258 envelopes

step by step explanation:

length of sheet of paper = 3m24cm or 324 cm

breadth of sheet of paper= 1m 72 cm or 172 cm

area of sheet of paper = L x B

                                     = 324 x 172

                                     = 55728 cm²

lenght of envelope = 18 cm

breadth of envelope =12 cm

area of envelope = 18 x 12

                             = 216 cm²

no. of sheets that can be made = $\frac{area of sheet}{area of envelope}$

                                                    = $\frac{55728}{216}$

                                                   =258

Ans: 258 envelopes can be made
