Given

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $:\red \Rightarrow \sf \purple{Length} = \pink {3 cm}$

• $:\red \Rightarrow \sf \purple {Breadth }=\pink{ 4 cm}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $: \red \Rightarrow \sf\purple{Area \: of \: Rectangle }= \pink{ ?}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Using Formula

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• ${: \red \Rightarrow \sf \purple{Area \: of \: Rectangle }= \pink{( Length ×Breadth)}}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${ : \red\implies \sf\pink{Area \: of \: Rectangle} = (\purple{3 × 4})( \purple{cm \times cm})}$

$:\red\implies \sf \pink{Area \: of \: Rectangle} = \purple{12\: cm²}$

$\large\boxed {\mathfrak{ \purple{Area }= \pink{12 \: {cm}^{2} }}}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore

The Area of Rectangle is 12 cm².
