The rectangle would be a square. The diagonal of the square is a diameter of the circle. One diagonal cuts the square into two 45-45-90 special triangles.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "circle, area \"pi%2Ar%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The diagonal and diameter, \"2r\".
\n" ); document.write( "Let x be the side length of one side of the square.
\n" ); document.write( "\"x%5E2%2Bx%5E2=%282r%29%5E2\"
\n" ); document.write( "and a picture would help you to see that.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2x%5E2=4r%5E2\"
\n" ); document.write( "\"x%5E2=2r%5E2\"
\n" ); document.write( "\"x=r%2Asqrt%282%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area of the square: \"r%5E2%2A2\", and area of the circle was \"pi%2Ar%5E2\".
\n" ); document.write( "Percentage?
\n" ); document.write( "\"highlight%28100%2A%282%2Fpi%29%29\"
\n" ); document.write( "
\n" );
