The length, width and diagonal of the rectangle form a right triangle. The diagonal is the hypotenuse (longest side of the triangle). Use the Pythagorean Theorem:\r
\n" ); document.write( "\n" ); document.write( "Let a = 24
\n" ); document.write( "Let b = 10
\n" ); document.write( "Let c = diagonal \r
\n" ); document.write( "\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\"
\n" ); document.write( "\"24%5E2+%2B+10%5E2+=+c%5E2\"
\n" ); document.write( "\"576+%2B+100+=+c%5E2\"
\n" ); document.write( "\"676+=+c%5E2\"
\n" ); document.write( "\"c+=+26\"
\n" ); document.write( "The diagonal is 26 cm.
\n" ); document.write( "
\n" );
