Question

how many envelopes can be made out of a sheet of paper 384 CM by 172 CM if each envelope requires a piece of piece of paper of size 16 cm by 12 CM

Answer 1

Area of rectangle = length × breadth


Area of sheet of paper = 384 × 172 = 66048 cm ^2

Area of piece of paper = 16 × 12 = 192 cm^2

No. of envelopes = Area of sheet of paper ÷ Area of piece of paper

= 66048 ÷ 192 = 344.

So 344 envelopes can be made.

Hope it helps.

Have a good day buddy.
