Question

Example 5: How many envelopes
can be made out of a sheet of paper
of dimensions 150 cm 95 cm, if one
envelope requires a piece of paper of
dimensions 19 cm x 25 cm?​

Answer 1

Answer:

30 Envelopes

Step-by-step explanation:

No. of envelopes that can be made =  $\frac{Dimensions. of .the .sheet. of .paper}{Dimensions.of .one. envelope}$

                                                           = $\frac{ 150 cm X 95 cm}{19 cm X 25 cm}$

                                                           = $\frac{\boxed{150cm} X 95 cm }{ 19cm X \boxed{25cm}}$

                                                           = 6 × $\frac{95cm }{19cm}$

                                                           = 6 × 5

                                                           = 30 Envelopes

Answer 2

Answer:

30 envelopes

Step-by-step explanation:

Area of envelope=19cm x 25cm=475cm²

Area of paper=150x95cm²=14250cm²

No.of envelopes can be be made=

$area \: of \: paper \div \: area \: of \: envelope$

=14250cm²/475cm²=30 envelopes
