Answer 2

Answer:

128 envelopes can be made

Step-by-step explanation:

length of rectangular sheet = 4m OR 400cm

width of rectangular sheet = 1.2m OR 120m

area of rectangular sheet = l × b

area = 400 × 120

area = 48000cm^2

Now, area of a envelope = 25 × 15

area = 375cm^2

So, No. of envelopes which can be made are,

= area of sheet / area of envelope

= 48000/375

= 128
