Question

can be made out of a rectangular
piece of paper of sides 75 dm
and 3 m, if each envelope
requires 90 cmof paper is

Answer 1

Answer:

The number of envelope can be formed = 250

Step-by-step explanation:

[The dimensions might be 75 cm, 3 m and 90$cm^{2}$ which are mentioned in problem ]

Given dimensions of rectangular piece

           length = 75  cm

          breadth = 3 m ( 1=100 cm ⇒ 3 m = 3 ×100 = 300 )  

 area of the rectangular piece = $lb$ = 75 (300)

                                                       = 22500  $cm^{2}$

the required paper for envelope = 90 $cm ^{2}$

  the number of envelopes can be formed

    = total area of paper ÷ the paper required for envelope

    = 2250000÷ 90  = $\frac{22500}{90}$ = 250
