Answer 1

Question:

$\to$The length of a sheet used to make a notebook  is 20 cm and its breadth is 16 cm. Find the area  of the sheet of paper.

To Find:

• Find the area of the sheet of paper ?

Given:

$\:\:\:\:\:\:\:$

• Length of a sheet = 20 cm
• Breadth of a sheet = 16 cm

$\:\:\:\:\:\:\:$

Solution:

$\:\:\:\:\:\:\:$

As we know that,

• Area of rectangle = length × breadth

$\:\:\:\:\:\:\:$

$\to$ Area of rectangle = 20 × 16

$\to$ Area of rectangle = 320$\rm{cm^2}$

Required Answer:

• The area of the sheet of paper is 320$\rm\bold{cm^2}$.

Formula Used:

• Area of rectangle = length × breadth

Answer 2

$\huge\sf\underline{Answer}:$
$\large\implies \sf 320cm^2$

$\huge\sf\underline{Solution}:$
$\\ \large\sf\underline{Given}:$
➽ Length of a sheet = 20cm
➽ Breadth of a sheet = 16cm

$\\ \large\sf\underline{To \: find}:$
➽ The area of the sheet of paper.


We know that,
$\bf \color{red} {Area \: of \: rectangle = \: length×breadth}$

So,

Area of sheet = Length × breadth
$\: \: \: \: \: \: \sf \implies 20×16 \\ \: \: \: \: \: \: \sf \implies 320cm^2$


Therefore,

$\bf The \: area \: of \: the \: sheet \: of \: paper \: is \: 320cm^2.$
