document.write( "Question 211816: An architect is using the concept of similar geometric figures and a small prototype model (shown on the right below) to design a cottage. For both the model and the actual cottage, the ratio of the height to the width (excluding the roof) is 9 to 12. If the width of the actual house is 8 ft, what is its height?

Using proportions:
\n" ); document.write( " Model -----------to---- actual
\n" ); document.write( "(Height/Width) = (height/width)
\n" ); document.write( " $\"9%2F12+=+h%2F8\"$ Multiply both sides by 8.
\n" ); document.write( " $\"9%2A8%2F12+=+h\"$ Evaluate.
\n" ); document.write( " $\"h+=+6\"$ feet.
\n" ); document.write( "The height (excluding roof) is 6 feet. \n" ); document.write( "

\n" );
