The area of the smaller rectangle is 160 cm sq.
\n" ); document.write( "2250/160 = 14.065.
\n" ); document.write( "\"sqrt%2814.065%29\" is our scale factor.
\n" ); document.write( "3.75 is our scale factor.
\n" ); document.write( "8 * 3.75 = 30, one dimension.
\n" ); document.write( "20 * 3.75 = 75, the other dimension.
\n" ); document.write( "30 cm *75 cm = 2250 cm.
\n" ); document.write( "This does check.
