Question

How many cards can be made out of sheet of paper meausering 330cm*12.1cm if each card requires a piece o paper of size 15*1.1cm

Answer 1

Answer:

• 242 cards can be made from the sheet.

Given :

• Area of sheet = 330 x 12.1

• Area of a card = 15 x 1.1

To find :

• Number of cards can be cut from sheet =?

Step-by-step explanation:

Area of sheet = Area of rectangle = l × b

= 330 x 12.1

= 3993

So, the area of sheet = 3993 cm²

Now,

Area of a card = Area of rectangle = l × b

= 15 x 1.1

= 16.5

So,the area of a card = 16.5 cm²

Number of cards can be made from sheet = Area of sheet /Area of a card

Substituting the values in the above formula, we get,

= 3993/16.5

= 242

Thus, 242 cards can be made from the sheet.

Answer 2

Answer:

${\underline{\boxed{\sf\purple{Number \: of \: cards \: can \: be \: made = 242 }}}}$

Given:-

• Measures of sheet=330 * 12.1 cm
• Measure of card = 15 * 1.1 cm

To find:-

• How many cards can be made ?

Solution:-

We know,

$\star \: {\boxed{\sf\pink{Area \: of \: rectangle = Length * Breadth }}}$

$\rightarrow\sf Area \: of \: sheet = (330 * 12.1) cm^2 \\\\\rightarrow\sf Area \: of \: sheet ={\boxed{\sf\red{ 3993 cm^2 }}}$

Now,

$\rightarrow\sf Area \: of \: card = (15 * 1.1) \: cm^2 \\\\\rightarrow\sf Area \: of \: card ={\boxed{\sf\pink{16.5 \: cm^2 }}}$

$\rule{200}{1}$

$\sf Now, No.\: of \: cards = \dfrac{Area \: of \: sheet}{Area \: of \: card } \\\\\rightarrow\sf No.\: of \: cards = \dfrac{3993}{16.5} \\\\\rightarrow\sf No.\: of \: cards = {\boxed{\sf\blue{242 }}}$

${\underline{\therefore{\bold\red{242 \: cards \: can \: be \: made .}}}}$
