Question 1166938
the area of the fence is currently 15 * 20 = 300 square feet.
to double the area, it needs to become 600 square feet.
each side would have to be equal to sqrt(600) = 24.49489743
round to two decimal places (nearest hundredth) to get 24.50 feet on each side.
the perimeter of the fence would be equal to 4 * 24.49489743 = 97.97958971.
round to two decimal places to get 97.98.


the formulas used are:
area = length * width for the rectangle.
area = side squared for the square.
perimeter = 2 * (length + width) for the rectangle).
perimeter = 4 * side for the square.


all rounding is done at the end of each calculation.
