First we find out the area of one tile: $\"10%2A10+cm%5E2\"$ = $\"100cm%5E2\"$ =\r
\n" ); document.write( "\n" ); document.write( " $\"0.01m%5E2\"$ .\r
\n" ); document.write( "\n" ); document.write( "To find how many tiles we need to cover $\"72m%5E2\"$ we divide:\r
\n" ); document.write( "\n" ); document.write( " $\"72%2F0.01=+7200\"$ .\r
\n" ); document.write( "\n" ); document.write( "Answer:We need 7200 tiles. \n" ); document.write( "
