The sides of a $\"30-60-90\"$ triangle are in ratio of $\"hsin%2830%29-hsin%2860%29-h=0.5h-%28sqrt%283%29%2F2%29h-h\"$
\n" ); document.write( "The perimeter would then be the sum of the three sides.
\n" ); document.write( " $\"P=0.5h%2B%28sqrt%283%29%2F2%29h%2Bh\"$
\n" ); document.write( " $\"P=20%281.5%2B%28sqrt%283%29%2F2%29%29\"$
\n" ); document.write( " or approximately,
\n" ); document.write( " $\"P=47.32\"$ cm \n" ); document.write( "
