I need help figuring out the formula for this problem. What might the lengths of a horse enclosure border be if the enclosure is 52 square feet? I have to show my work. Please can someone help me figure it out?

well, if it were square
L*L= 52
or L = 7.21
or if it were a circle
circumference = 2 pi r
area = pi r^2 = 52
r = 4.07
2 pi r = length of circular fence = 25.6 ft
Of course it could be lots of different rectangles
for example 4 feet by 13 feet
or 8 feet by 6 1/2 feet
