Answer 1

Answer:

If 17cm×5 cm paper is required to make an envelope, then  156 envelopes can be prepared from a paper of 130cm× 102cm.​

Step-by-step explanation:

If 17cm×5 cm paper is required to make an envelope.

Then Area of envelope = 17cm×5 cm  = 85 sq. cm

Total paper provided = 130cm× 102cm

Area of given paper =  130cm× 102cm  = 13260 sq. cm

So number of envelopes can be prepared from a paper of 130cm× 102cm

= 13260  ÷ 85

= 156  

So, 156 enveloped can be prepared.
