The area doesn't tell you the shape or the perimeter. Even if you restrict it to

rectangles, there are an infinite number of those, all with different perimeters,

that all have 42 ft squared of area.

Here are a few of them. ALL of the areas are 42 ft squared.

42 ft by 1 ft (perimeter = 86 ft)

21 ft by 2 ft (perimeter = 46 ft)

14 ft by 3 ft (perimeter = 34 ft)

12 ft by 3ft6in (perimeter = 31 ft)

7 ft by 6 ft (perimeter = 26 ft)

If you're trying to make a square out of it, then the length of each side of the square

is sqrt(42), and the perimeter is 25.92 to the nearest hundredth.

On the other hand, it could be a circle, and the perimeter (circumference) of the circle

is 22.97 to the nearest hundredth.
