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
