Question

how many envelopes can be made out of sheet of paper 72cm by 48cm. If each envelope requires a paper of size 18cm by 12cm?

Answer 1

The dimension of paper :-

length (l) = 72 cm

Breadth (d) = 48 cm

The dimension of envelope :-

length (l) = 18 cm

Breadth (b) = 12 cm

Therefore,

No. of envelopes can be made = Area of paper/ Area of envelopes

Area of paper = l × b

= 72 × 48

= 3,456 cm^2

Area of envelop = l × b

= 18 × 12

= 216 cm^2

No. of envelopes = 3,456 / 216

= 16

Therefore, 16 envelops can be made from a paper of 72 cm by 48 cm.
