What are the dimensions of a square hectare in feet?

Answer 1

One hectare is defined as an area of 10,000 square meters, or about 107,639 square feet.

This doesn't tell you anything about its shape or linear dimensions. It could be a circle with a radius of about 56 meters, a square with 100-meter sides, millions of rectangles of different lengths and widths (just as long as the product of (length x width) is 10,000), or millions of other shapes.
