Same y-value:
\n" ); document.write( "( 28, 40 )
\n" ); document.write( "( 8, 40 )
\n" ); document.write( "The x distance across is \"+28+-+8+=+20+\"
\n" ); document.write( "Same x-value:
\n" ); document.write( "( 18, 64 )
\n" ); document.write( "( 18, 16 )
\n" ); document.write( "The y distance top to bottom is \"+64+-+16+=+48+\"
\n" ); document.write( "———————-
\n" ); document.write( "\"+20%2F2+=+10+\"
\n" ); document.write( "\"+48%2F2+=+24+\"
\n" ); document.write( "\"+c+=+sqrt%28+10%5E2+%2B+24%5E2+%29+\"
\n" ); document.write( "\"+c+=+sqrt%28+676+%29+\"
\n" ); document.write( "\"+c+=+26+\"
\n" ); document.write( "This is the length of one side, so
\n" ); document.write( "\"+4%2A26+=+104+\" is the length of tape
\n" ); document.write( " \n" ); document.write( "
\n" );
