let the length and breadth of sheet of paper be L and B.

let the length and breadth of paper required to make the envelope be l and b.

area of sheet=L*B

                     =249*72

                     =17928 cm²

area of sheet required for 1 envelope=l*b

                                                              =18*12

                                                              =216 cm²

no. of envelopes that can be made=(L*B)/(l*b)

                                                          =17928/216

                                                          =83

so,83 envelopes can be made from the sheet provided.
