Base length = b
\n" ); document.write( "Equal leg length = 4b - 8
\n" ); document.write( "\"%28side%29+%2B+%28side%29+%2B+%28side%29+=+Perimeter\"
\n" ); document.write( "\"%284b+-+8%29+%2B+%284b+-+8%29+%2B+%28b%29+=+29\"
\n" ); document.write( "\"9b+-+16+=+29\"
\n" ); document.write( "\"9b+=+45\"
\n" ); document.write( "\"b+=+5\"
\n" ); document.write( "Equal leg length = \"4b+-+8\"
\n" ); document.write( "\"4%285%29+-+8\"
\n" ); document.write( "\"20+-+8\"
\n" ); document.write( "\"12\"
\n" ); document.write( "
