width =x
\n" ); document.write( "length = 2x-3\r
\n" ); document.write( "\n" ); document.write( "Perimeter =78\r
\n" ); document.write( "\n" ); document.write( "Perimeter = 2(x+2x-3)
\n" ); document.write( "2(3x-3)=78
\n" ); document.write( "6x-6=78
\n" ); document.write( "6x=84
\n" ); document.write( "/6
\n" ); document.write( "x=14 the width
\n" ); document.write( "length = 2*14-3=25 inches
\n" ); document.write( "
