You can put this solution on YOUR website!
I am going to use a suffix of M to indicate dimensions of the model.\r
\n" ); document.write( "\n" ); document.write( "Given:
\n" ); document.write( "LM = 15ft
\n" ); document.write( "WM = 3ft
\n" ); document.write( "HM = 1ft
\n" ); document.write( "L = 12000ft
\n" ); document.write( "-------------
\n" ); document.write( "To find the scale used you need to compare like dimensions. In this example we are given both lengths.\r
\n" ); document.write( "\n" ); document.write( "Find the scale of the model: $\"L%2FLM\"$
\n" ); document.write( " $\"12000%2F15+=+800\"$
\n" ); document.write( "Multiply the other model dimensions by 800 to find their actual values in real life.\r
\n" ); document.write( "\n" ); document.write( "W = 3ft * 800
\n" ); document.write( "W = 2400ft\r
\n" ); document.write( "\n" ); document.write( "H = 800 * 1ft
\n" ); document.write( "H = 800ft \n" ); document.write( "

\n" );
