length : breadth = 3 : 2
\n" ); document.write( "Let length = 3x, breadth = 2x\r
\n" ); document.write( "\n" ); document.write( "Area of rectangle = length * breadth
\n" ); document.write( " $\"9600+=+3x+%2A+2x\"$
\n" ); document.write( " $\"9600+=+6x%5E2\"$
\n" ); document.write( " $\"x%5E2=9600%2F6\"$
\n" ); document.write( " $\"x%5E2=1600\"$
\n" ); document.write( " $\"x=sqrt%281600%29\"$
\n" ); document.write( "x = 40
\n" ); document.write( "length = 3x = 3 * 40 = 120 cm
\n" ); document.write( " \n" ); document.write( "
