m wide. if each envelope needs a paper size 20cm x 8 cm​

Answer 1

Answer:

Area of sheet=15mx8m=1200000 sq cm

Area of one envelope=20cmx8cm=160 sq cm

Number of envelopes which can be fit= 1200000/160=7500

Thus,7500 envelopes can be made

Hope it helps!!!

Answer 2

Let number of envelopes that can be made = $x$

Area of one envelope ×  $x$ = Area of sheet of paper

$20*8*x = 1500*800$

$x = 7500$

That is, 7500 envelopes  can be made
