let the length be x inches\r
\n" ); document.write( "\n" ); document.write( "the width is 1/2 x\r
\n" ); document.write( "\n" ); document.write( "Perimeter = 2L+2W\r
\n" ); document.write( "\n" ); document.write( "2x+2*1/2 x = 72\r
\n" ); document.write( "\n" ); document.write( "2x+ 5x/2 = 72\r
\n" ); document.write( "\n" ); document.write( "4x+5x / 2 =72
\n" ); document.write( "9x= 144
\n" ); document.write( "x=16 inches\r
\n" ); document.write( "\n" ); document.write( "The length is 16 inches\r
