You can put this solution on YOUR website!
the original length of the square side's is 9cm.
\n" ); document.write( "u may reach this solution by considering the original side as x (variable)
\n" ); document.write( "area of the square is s^2 where s is the side length = x+8
\n" ); document.write( "then (x+8)^2=289
\n" ); document.write( "taking the square root of both sides then x+8=17
\n" ); document.write( "then x=17-8=9cm \n" ); document.write( "

\n" );
