The area of the 3cm tile is \"0.03m%2A0.03m=9%2A10%5E%28-4%29+m%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The area of the room is \"3m%2A4.5m=13.5%2Am%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "How many of the small areas are in the big area?
\n" ); document.write( "\"%2813.5%29%2F%280.0009%29=highlight%2815000%29\"----that is how many of the 3 cm tiles will fit.
