Let $\"S\"$ be the equal length side.
\n" ); document.write( " $\"B=2S-3\"$
\n" ); document.write( " $\"B%2BS%2BS=37\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"2A-3%2BS%2BS=37\"$
\n" ); document.write( " $\"4S=40\"$
\n" ); document.write( " $\"S=10\"$ cm
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"B=2%2810%29-3\"$
\n" ); document.write( " $\"B=17\"$ cm \n" ); document.write( "
