How big is one hundred acres what is an apt comparison?

Answer 1

A "section" of farmland is a 1-mile-by-1-mile square. There are networks of roads laid
out on a grid of 1-mile intervals in many parts of the USA, especially in the expanses
of wheat and corn in the Great Plains states.

Each 'section' encloses 1 square mile of land, also equal to 640 acres. So when you
look down from an airliner in flight and see the checkerboard pattern of 1-square-mile
sections, you may be able to visualize that 100 acres fits into one of those squares
6.4 times.

-- If 100 acres were to be enclosed in a square plot, then that square would have to be
2,087 feet (695.7 yards) on each side ... about 0.395 of a mile.

-- The playing area of an an official NFL football field, including end-zones, is
120-yards long and 160-feet (531/3 yards) wide. That area is 1.322 acres. (rounded)
Your 100 acres covers 755/8 regulation NFL football fields.
