Slightly distracting way to give the perimeter of 17 feet, but the emphasis is on dimensions of a rectangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "w for width
\n" ); document.write( "L for length, \"tallness\"
\n" ); document.write( "Perimeter is 2w+2L=17.
\n" ); document.write( "The description for w and L is \"L=1%2B2w\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The perimeter is not an even number, so just do the substitution of L into the perimeter equation:
\n" ); document.write( "\"2w%2B2%282w%2B1%29=17\"\r
\n" ); document.write( "\n" ); document.write( "\"2w%2B4w%2B2=17\"
\n" ); document.write( "\"6w=15\"
\n" ); document.write( "\"w=15%2F6\"
\n" ); document.write( "\"highlight%28w=5%2F2%29\"
\n" ); document.write( "This means \"L=2%285%2F2%29%2B1\"
\n" ); document.write( "\"L=5%2B1\"
\n" ); document.write( "\"highlight%28L=6%29\"
\n" ); document.write( "(Fixed mistake)
\n" ); document.write( "
