A, the given area with tiles
\n" ); document.write( "x, edge length of the original tile size\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"128x%5E2=A\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "New tile size, x-2, area A uses 200 of these tiles.
\n" ); document.write( "\"200%28x-2%29%5E2=A\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two area both are A.
\n" ); document.write( "\"128x%5E2=200%28x-2%29%5E2\"
\n" ); document.write( "Simplify and solve for x.
\n" ); document.write( "
\n" );
