What is the greatest perimeter of a rectangle with an area of 39 square feet?

Answer 1

I think you got it backwards. You want the minimium perimeter, not the max
e.g. I could have a rectangle of .05 ft by 780 ft, with a perimeter of 156.01 ft
I can make the width smaller and smaller and the perimeter would get bigger and bigger

for the smallest perimeter, the rectangle should be a square and its perimeter is
4√39 = ..... ft
