How large is an acre?

well an acre is about 76 percent of a football field

i've been told an acre is about the size of a football field

An acre is 43,560.18 square feet. Which is about 209 feet by 209 feet, provided the acre is an exact square, not an irregular shape. 209 feet is about 150 feet shorter than a football field (including end zones), but it is about 50 feet wider than a football field. So the dimensions are a bit different to get an actual idea of how big. All in all, an acre is smaller than a football field. A football field has an area of 57,600 square feet. (about 14,040 more square footage than an acre).

The average football field is about 1 acre. A suburban house lot is often 1/5 acre and the slightly larger ones are 1/4 acre. Call it a square 209 feet on a side and you will not be far out. 200 people would fit on a acre easily. There would be plenty of room to sit down but you could not have 200 cars as well.

http://en.wikipedia.org/wiki/Acre set a table on every yard line marker and there is still room to walk around them and have aisles between.... consider a small church's seating area.... see the last floorplan here... http://www.digitalchurchplans.com/products.php?cat=7 that's just seats, the whole area would make them comfy... six thousand square feet.....

You can fit 200 cars parked up correctly in 1 acre.

1 acre is 660 ft X66 ft=43560 sq ft or however u change dimensions

200 people + picnic tables should fit on a half acre` space
