\n" ); document.write( "The \"Area\" of the bedroom is 4mx5m= \"20m%5E2\"
\n" ); document.write( "And the wallpaper roll can only cover an \"Area\" of \"6m%5E2\" ----> 6mx 1m
\n" ); document.write( "So, you need 4
\n" ); document.write( "rolls to cover the room Area----> \"4+x+6m%5E2\" ---> \"24m%5E2\". This is enough because the room is only \"20m%5E2\"\r
