4B-8=ONE OF THE EQUAL LEGS.
\n" ); document.write( "THUS THE PERIMETER IS:
\n" ); document.write( "2(4B-8)+B=29
\n" ); document.write( "8B-16+B=29
\n" ); document.write( "9B=29+16
\n" ); document.write( "9B=45
\n" ); document.write( "B=45/9
\n" ); document.write( "B=5 ANSWER FOR THE LENGTH OF THE BASE.
\n" ); document.write( "4*5-8=12 FOR EACH OF THE EQUAL LEGS.
\n" ); document.write( "PROOF
\n" ); document.write( "2*12+5=29
\n" ); document.write( "24+5=29
\n" ); document.write( "29=29
