length of rectangle is twice as much as its breadth. if the perimeter is 120cm, the length of the rectangle is:
\n" ); document.write( "let x=breadth of rectangle
\n" ); document.write( "2x=length of rectangle
\n" ); document.write( "twice the breadth+twice the length=perimeter
\n" ); document.write( "2x+4x=120
\n" ); document.write( "6x=120
\n" ); document.write( "x=20
\n" ); document.write( "2x=40
\n" ); document.write( "the length of the rectangle is: 40 cm
\n" ); document.write( "
\n" );
