Find the total area to cover the ceiling.
\n" ); document.write( "The ceiling is in the shape of a rectangle.
\n" ); document.write( "The area of a rectangle is length times width.
\n" ); document.write( "\"A=L%2AW=21%2A18\"sq.ft.
\n" ); document.write( "Each tile is a 1'x1' square and has an area of 1 sq. ft.
\n" ); document.write( "Divide the total area by the area of one tile to find out how many tiles you need.
\n" ); document.write( "\"N=A%2F1\"
\n" ); document.write( "The total cost is $3 times the number of tiles.
\n" ); document.write( "\"C=3N=%283A%29%2F1=%283%2A21%2A18%29%2F1\" in dollars.
