\n" ); document.write( "\n" ); document.write( "is totally wrong!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To estimate the numbers of circles,  you should divide the area of the fabric  5 m x 1.3 m \r
\n" ); document.write( "\n" ); document.write( "(or,  better,  4.96 m x 1.28 m)  by the area of the  square  with the side of  8 cm.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You have  \"496%2F8\" = 62  sizes of the square along the the longer side of the fabric and  \"128%2F8\" = 16 \r
\n" ); document.write( "\n" ); document.write( "sizes of the square along the shorter sides.  In total,  there are  62*16 = 992  such squares.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There is another pattern,  which seems more promising.  It is the pattern where the centers \r
\n" ); document.write( "\n" ); document.write( "of circles are located in the vertices of equilateral triangles.  Although it is elementary to analyse \r
\n" ); document.write( "\n" ); document.write( "such a pattern,  it seems to be still above of the average school level,  therefore \r
\n" ); document.write( "\n" ); document.write( "I am not placing such an analysis here.\r
