\n" ); document.write( "Let x = length of diagonal of the rectangle
\n" ); document.write( "Using Pythagorean Theorem:
\n" ); document.write( "\"x%5E2+=+7%5E2+%2B+12%5E2\"
\n" ); document.write( "\"x%5E2+=+193\"
\n" ); document.write( "Therefore, \"x+=+highlight%28sqrt%28193%29%29\" cm or 13.89 cm [correct to 2 decimal places]
