W=width; L=length=W+9in; P=perimeter=2(L+W)=122in
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "122in=2(L+W) Divide each side by 2.
\n" ); document.write( "61in= L+W Substitute for L.
\n" ); document.write( "61in=W+9in+W Subtract 9in from each side.
\n" ); document.write( "52in=2W Divide each side by 2.
\n" ); document.write( "26in=W ANSWER 1: The width is 26 inches.
\n" ); document.write( "L=W+9in=26in+9in=35in ANSWER 2: The length is 35 inches.
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "122in=2(35in+26in)
\n" ); document.write( "122in=2(61in)
\n" ); document.write( "122in=122in
\n" ); document.write( "
\n" ); document.write( "
