What is the distance from the center to the edge of 10000 square feet?

Answer 1

The answer depends on the shape: it can be any distance at all.

Consider 10,000 square feet in the shape of a 10,000 ft x 1 ft rectangle. The distance from the centre to the edge can be as small as 0.5 ft or as large as 50,000 ft (approx 9.5 miles).

Or consider a rectangle that is 1,000,000 ft x 0.01 ft. The distance can now be as small as 0.005 ft (0.06 inches) or as large as 500,000 ft (95 miles).
