Originally let the sides be $\"x\"$ cm.
\n" ); document.write( " $\"%28x%2B6%29%5E2=100\"$
\n" ); document.write( " $\"x%5E2%2B12x%2B36=100\"$
\n" ); document.write( " $\"x%5E2%2B12x-64=0\"$
\n" ); document.write( " $\"%28x-4%29%28x%2B16%29=0\"$
\n" ); document.write( "Two solutions but only the positive solution makes sense here.
\n" ); document.write( " $\"x-4=0\"$
\n" ); document.write( " $\"highlight%28x=4%29\"$ cm
\n" ); document.write( "Correct.
\n" ); document.write( "Well done! \n" ); document.write( "
