What is the shape, a rectangle, square, or circle. If it is a rectangle, you need at least the value of length or width. If it is a square then the perimeter is

4 x (square root of 850) = 4 x 29.15 = 116.6 feet

If it is a circle, then (pi x r x r) = 850

That is 3.1415 x r x r = 850

r squared is 850/3.1415 = 270.57

Hence r is 16.45

Now the perimeter (or circumference) is pi x 2 x r = 3.1415 x 2 x 16.45 = 103.35 ft

So it is important to know the shape of the area.
