Diagram :

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 12 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 8 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

$\qquad \bigstar \:\underline{ \bf{ Perimeter \:of \:Rectangle \:\::\:}}\:$

$\qquad \dashrightarrow \sf Perimeter \: \:=\: 2 \:( \:Length \:+\:Breadth \:)\:\:\\\\ \qquad \dashrightarrow \sf Perimeter \:\:=\: 2 \:( \:12 \:+\:8 \:)\:\:\\\\\qquad \dashrightarrow \sf Perimeter \: \:=\: 2 \:( \:20 \:)\:\:\\\\\qquad \dashrightarrow \sf Perimeter \:\:=\: 40\:\:\\\\\qquad \dashrightarrow \sf Perimeter \: \:=\: 40 \:cm\:\:$

$\qquad \therefore \:\underline {\sf Hence, \: The\:Perimeter \:of \:Rectangle \:\:is \:\pmb{\bf 40 \:cm \:}\:}$
