Suppose that a rectangle has an area of 89 square meters.
\n" ); document.write( " Express the perimeter P as a function of the length x of one of the sides.
\n" ); document.write( ":
\n" ); document.write( "Rectangle: x by W
\n" ); document.write( ":
\n" ); document.write( "x * W = 89
\n" ); document.write( "W = $\"89%2Fx\"$
\n" ); document.write( ":
\n" ); document.write( "P = 2x + 2W
\n" ); document.write( "Replace W with $\"89%2Fx\"$
\n" ); document.write( "P = 2x + 2( $\"89%2Fx\"$ )
\n" ); document.write( "P = 2x + $\"178%2Fx\"$ \n" ); document.write( "

\n" );
