Perimeter of rectangle is 2*length+2*width \n" ); document.write( "but l=3w \n" ); document.write( "p=2l+2w=2(3w)+2w=8w,,,but given =240 \n" ); document.write( "therefore w=240/8, =30\r \n" ); document.write( "\n" ); document.write( "and l=3w=3*30=90 \n" ); document.write( "check \n" ); document.write( "Per=2(30)+2(90)=60+180=240,,,,ok \n" ); document.write( " |
