Given :

  • Area of rectangle = 132 cm²
  • Breadth of rectangle = 6 cm

⠀⠀⠀⠀⠀⠀⠀

To find :

  • Length of Rectangle?

⠀⠀⠀⠀⠀⠀⠀

Solution :

⠀⠀⠀⠀⠀⠀⠀

☯ Let length of Rectangle be x cm.

⠀⠀⠀⠀⠀⠀⠀

\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large x cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 6 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}

⠀⠀⠀⠀⠀⠀⠀

We know that,

⠀⠀⠀⠀⠀⠀⠀

:\implies{\boxed{\sf{\purple{Area_{\;(Rectangle)} = length \times breadth}}}}\\ \\

Now, Putting values,

⠀⠀⠀⠀⠀⠀⠀

:\implies\sf x \times 6 = 132\\ \\

:\implies\sf x = \cancel{ \dfrac{132}{6}}\\ \\

:\implies{\boxed{\sf{\pink{x = 22\;cm}}}}\;\bigstar\\ \\

\therefore\;{\underline{\sf{Hence,\; Length\;of\;rectangle\;is\; \bf{22\;cm}.}}}

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

\qquad\qquad\boxed{\underline{\underline{\bigstar \: \bf\:More\:to\:know\:\bigstar}}} \\  \\

  • Perimeter of Rectangle = 2(l + b)

  • Diagonal of Rectangle = \sf \sqrt{l^2 + b^2}

  • Area of square = side × side

  • Perimeter of square = 4 × side

  • Diagonal of square = \sf a \sqrt{2}

Question :

To find length of Rectangle

Solution :

Given ::

  • Area of rectangle = 132 cm²
  • Breadth = 6 cm

{\underline{\boxed{\bf{area \: of \: Rectangle \:  = l \times b \:  \: }}}}

  • l = length
  • b = breadth

Let's do ::

let, Length be x ,

\sf \longrightarrow \:  x  \: \times 6 = 132 \\  \\\sf\longrightarrow  \: x =  \frac{132}{6}  \\  \\ \bf\longrightarrow \: x = 22

So, Length is 22 cm.

let's verify ::

 =  > \sf \: l \:  \times b \:  = 132

 =  > \sf \: 22 \times 6 = 132

 =  > \sf \: 132 = 132

 \bf \: LHS \:  =  \: RHS \:

Thus Solved !!
