The diameter of the semicircle is equal to \"D=20\" cm.
\n" ); document.write( "The perimeter of the semicircle is,
\n" ); document.write( "\"P%5Bsc%5D=pi%2AR=pi%2820%2F2%29=10pi\"
\n" ); document.write( "So then adding the two sides of the triangle,
\n" ); document.write( "\"P=10pi%2B20%2B20\"
\n" ); document.write( "\"P=40%2B10pi\"\"cm\"
\n" ); document.write( "
