(10+x)(13+x)=208
\n" ); document.write( "130+23x+x^2=208
\n" ); document.write( "x^2+23x+130-208=0
\n" ); document.write( "x^2+23x-78=0
\n" ); document.write( "(x+26)(x-3)=0
\n" ); document.write( "x-3=0
\n" ); document.write( "x=3 ans. for the additional increase of the length & width.
\n" ); document.write( "Proof:
\n" ); document.write( "(10+3)(13+3)=208
\n" ); document.write( "13*16=208
\n" ); document.write( "208=208
\n" ); document.write( "
