Question

how many notebooks can be made out of sheet of paper 105 CM by 22 CM if each notebook requires a piece of paper of Size 15 CM by 2 cm

Answer 1

$area \: of \: sheet \: = 105 \times 22 = 2310 \: cm {}^{2} \\ \\ \\ area \: of \: a \: piece \: of \: paper \: of \: each \: notebook = 15 \times 2 \\ \\ = 30 \: cm {}^{2} \\ \\ therefore \: number \: of \: notebooks \: = \frac{area \: of \: \: the \: whole \: sheet}{area \: of \: one \: notebook} \\ \\ = \frac{2310}{30} \\ \\ = 77 \\ \\ \\ hope \: it \: helps...$

Answer 2

Answer

77 Notebook


First , in the questions given dimensions sheet of paper 105 cm length and breadth 22cm.

Now,

We calculate Area of sheet of paper = length × breadth

We putting the Values in formula

l × b = 105cm × 22cm

${2310cm}^{2}$

Area of 1 Sheet of paper there dimensions are 15 cm length and 2Cm breadth .


We find area of the 1 sheet of paper = l × b.

$l \times b = 15cm \times 2cm = {30cm}^{2}$


Here be find how many Notebook made from total sheets Paper.

then ,



$= \frac{area \: of \: the \:total \: notebook \: sheet \: of \: paper}{area \: of \: the \:one \: notebook \: sheet \: of \: paper } \\ \\ = \frac{ {3101cm}^{2} }{ {30cm}^{2} } \\ \\ = 77 \: notebook$
