sol:
\n" ); document.write( "let the width be x
\n" ); document.write( "twice the width=2x
\n" ); document.write( "length=5 less than the twice the width
\n" ); document.write( "length=2x-5
\n" ); document.write( "perimeter of the rectangle=2*(length+width)
\n" ); document.write( " =2*(2x-5+x)
\n" ); document.write( " =2*(3x-5)
\n" ); document.write( " =2*3x-2*5
\n" ); document.write( " =6x-10
\n" ); document.write( "according to the problem perimeter=50 cm
\n" ); document.write( " 6x-10=50
\n" ); document.write( "adding 10 on both sides
\n" ); document.write( "6x-10+10=50+10
\n" ); document.write( "6x=60
\n" ); document.write( "dividing by 6 on both sides
\n" ); document.write( "6x/6=60/6
\n" ); document.write( "x=10
\n" ); document.write( "width=10 cm
\n" ); document.write( "length=2x-5
\n" ); document.write( " =2*10-5
\n" ); document.write( " =20-5
\n" ); document.write( " =15 cm\r
\n" ); document.write( "\n" ); document.write( "length=15cm,width=10cm
\n" ); document.write( "
