The Phytagorean Theorem can be applied!\r
\n" ); document.write( "\n" ); document.write( "Let a=x(the length)
\n" ); document.write( "____b=x-2(the width)
\n" ); document.write( "____c=10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thus,\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B%28x-2%29%5E2=10%5E2\"
\n" ); document.write( "\"x%5E2%2B%28x%28x-2%29-2%28x-2%29%29=100\"
\n" ); document.write( "\"x%5E2%2B%28%28x%5E2-2x%29-%282x-4%29%29=100\"

\n" ); document.write( "\"2x%5E2-4x-4=100\"
\n" ); document.write( "\"2x%5E2-4x-104=0\"\r
\n" ); document.write( "\n" ); document.write( "By the quadratic formula,\r
\n" ); document.write( "\n" ); document.write( "\"x=%284%2B-sqrt%284%5E2-4%2A2%2A%28-104%29%29%29%2F%282%2A2%29\"

\n" ); document.write( "\n" ); document.write( "We will eliminate the \"x=%284-29.120439557122%29%2F%284%29\" part 'coz it will be only negative---an impossible result\r

\n" ); document.write( "\n" ); document.write( "\"x=%284%2B29.120439557122%29%2F%284%29=33.120439557122%2F4=8.2801098892805\"\r
\n" ); document.write( "\n" ); document.write( "Thus, the length is 8.2801098892805 units long\r
\n" ); document.write( "\n" ); document.write( "If x=8.2801098892805, then x+2=10.2801098892805\r
