Hi there,
\n" ); document.write( "Convert your wall measurements into
\n" ); document.write( "cm. 2.7m = 270cm, 2.25m = 225cm
\n" ); document.write( "3m = 300cm
\n" ); document.write( "Area of long wall = 300cm x 270
\n" ); document.write( "= 81000cm^2
\n" ); document.write( "Area of short wall = 300cm x 225cm
\n" ); document.write( "= 67500cm^2
\n" ); document.write( "2 Long walls = 162,000cm^2
\n" ); document.write( "2 Short walls = 135000Cm^2
\n" ); document.write( "...........
\n" ); document.write( "162,000 + 135000 =297000cm^2
\n" ); document.write( "Area of tile = 15cm x 15 cm = 225cm^2
\n" ); document.write( "297000/225 = 1320 tiles
\n" ); document.write( "Hope this helps:-)
