S=2L-2
\n" ); document.write( "P=2L+S
\n" ); document.write( "46=2L+2L-2
\n" ); document.write( "42=4L-2
\n" ); document.write( "4L=42+2
\n" ); document.write( "4L=44
\n" ); document.write( "L=44/4
\n" ); document.write( "L=11 ANS. FOR THE 2 EQUAL LENGTHS.
\n" ); document.write( "S=2*11-2
\n" ); document.write( "S=2*11-2=22-2=20 ANS. FOR THE SIDE.
\n" ); document.write( "PROOF:
