Suppose that the expression $\"%28x%5E2%2B7x%2B12%29%2F%28x%2B2%29%5E2\"$ represents the area of a rectangle.
\n" ); document.write( "Find the expression for the perimeter of the rectangle.
\n" ); document.write( ":
\n" ); document.write( "Factor $\"%28x%5E2%2B7x%2B12%29%2F%28x%2B2%29%5E2\"$
\n" ); document.write( ":
\n" ); document.write( " $\"%28%28x%2B4%29%28x%2B3%29%29%2F%28%28x%2B2%29%28x%2B2%29%29\"$
\n" ); document.write( "then A=L*W, therefore we can say:
\n" ); document.write( " $\"%28x%2B4%29%2F%28x%2B2%29\"$ = the length
\n" ); document.write( "and
\n" ); document.write( " $\"%28x%2B3%29%2F%28x%2B2%29\"$ = the width
\n" ); document.write( ":
\n" ); document.write( "P = 2( $\"%28x%2B4%29%2F%28x%2B2%29\"$ ) + 2( $\"%28x%2B3%29%2F%28x%2B2%29\"$ ) = ( $\"%282x%2B8%29%2F%28x%2B2%29\"$ ) + ( $\"%282x%2B6%29%2F%28x%2B2%29\"$ ) \n" ); document.write( "

\n" );
