Question

How many envelopes of size 25 cm by 5 cm can be made from a rectangular papersheet of size 2 m by 80 cm?​

Answer 1

Answer:

=area of rectangular sheet=80cm*200cm=16000

=area of envelope=25cm*5cm=125cm

=no.of envelope=16000/125=128 envelops

Answer 2

There are 12 envelopes can be made.

Step-by-step explanation:

Since we have given that

Dimension of envelopes = 25 cm by 5 cm

So, length = 25 cm

width = 5 cm

So, Area would be $length\times width=25\times 5=125\ cm^2$

Dimension of papersheet = 2 m by 80 cm

So, length = 2 m = 200 cm

Width = 80 cm

So, Area would be $length\times width=200\times 80=1600\ cm^2$

So, Number of envelopes would be

$\dfrac{\text{Area of papersheet}}{\text{Area of envelope}}\\\\=\dfrac{1600}{125}\\\\=12.8\\\\\approx 12$

Hence, there are 12 envelopes can be made.
