the area of the fence is currently 15 * 20 = 300 square feet.
\n" ); document.write( "to double the area, it needs to become 600 square feet.
\n" ); document.write( "each side would have to be equal to sqrt(600) = 24.49489743
\n" ); document.write( "round to two decimal places (nearest hundredth) to get 24.50 feet on each side.
\n" ); document.write( "the perimeter of the fence would be equal to 4 * 24.49489743 = 97.97958971.
\n" ); document.write( "round to two decimal places to get 97.98.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formulas used are:
\n" ); document.write( "area = length * width for the rectangle.
\n" ); document.write( "area = side squared for the square.
\n" ); document.write( "perimeter = 2 * (length + width) for the rectangle).
\n" ); document.write( "perimeter = 4 * side for the square.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "all rounding is done at the end of each calculation.\r
