For an equilateral triangle,
\n" ); document.write( " $\"A=%28sqrt%283%29%2F4%29s%5E2\"$
\n" ); document.write( "So if $\"s%5B2%5D=%281%2F2%29s%5B1%5D\"$
\n" ); document.write( " $\"A%5B2%5D%2FA%5B1%5D=s%5B2%5D%5E2%2Fs%5B1%5D%5E2\"$
\n" ); document.write( " $\"A%5B2%5D%2FA%5B1%5D=%28%281%2F2%29s%5B1%5D%5E2%29%2Fs%5B1%5D%5E2\"$
\n" ); document.write( " $\"A%5B2%5D%2FA%5B1%5D=1%2F4\"$
\n" ); document.write( "Since the new area is $\"1%2F4\"$ of the old area, the decrease is $\"3%2F4\"$ or $\"75\"$ %.
\n" ); document.write( " \n" ); document.write( "
