Original square,
\n" ); document.write( "x and x for length and width
\n" ); document.write( "Perimeter: 4x
\n" ); document.write( "Area: x^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Increased square,
\n" ); document.write( "x+4 and x+8 for length and width
\n" ); document.write( "Perimeter: \"2%28x%2B4%2Bx%2B8%29=2%282x%2B12%29=4x%2B48\"
\n" ); document.write( "Area: \"%28x%2B4%29%28x%2B8%29=x%5E2%2B12x%2B32\"\r
\n" ); document.write( "
\n" ); document.write( "

\n" ); document.write( "If the resulting rectangle has an area of 239.25 square feet
\n" ); document.write( "--------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B12x%2B32=239.25\"
\n" ); document.write( "Simplify and solve this for x, before finding the value of 4x.
\n" ); document.write( "
\n" );
