Question

How many envelopes can be made out of a sheet of paper 384 cm by 172 cm, if each envelope requires a piece of paper of size 16 cm by 12 cm?

Answer 1

idk if this is the correct answer but i hope it atleast gives u an idea of how it's done:

area of sheet = 384 * 172

                      = 66048 m^2

area of 1 envelope= 16* * 12

                              = 192 m^2

area of sheet / area of 1 envelope = 66048 / 192

                                                        = 344  

Answer 2

Answer:

344 Envelopes.

Step-by-step explanation:

Area of sheet = (384×172)square.cm

= 66048 square.cm

Area of paper for 1 envelope

= (16×12)square.cm

=192 square.cm

∴ Number of envelopes can be made

= 66048

192

= 344 Envelopes

Hope it helps you!
