I know an acre is approx. 43,560 Sq.ft. If one wanted to know how big of a square chunk of land this was.. what is the formula for finding out the lengths of the sides to find out how big the area would be in ft? (ex. one square 3/4 of a mile long, 3/4 mile wide etc.)??? thanks

An acre in a perfect square is 208 feet by 208 feet. I saw a good thread on this topic here

It is a moving calculation but you can calculate acreage of any length and width of property using an on-line acreage conversion calculator.

"The usual land tract under the Homestead Act in the United States is 160 acres or 0.25 square miles."
So we can start from there: 160 ares = 0.25 square mildes.
1 acre = 1 acre (0.25 miles^2/160 acres)(5280 ft/1 mile)^2 = 43,560 ft^2

Yes, an acre is 43,560 feet. There are 640 acres in a square mile.

There are 640 acres in a square mile, which is 27,878,400 square feet, so one acre is 43,560 square feet. An exactly square acre would be 208.710 feet = 0.0395284 mile on each side.
Gotta love our English units of measure...

An acre of land is approximatley 70 yards by 70 yards square
the exact measurement can be obtained by taking the root of the area (43,560) = 208.71 feet or 69.5 yards

To find a large area with many different sides you have to divide the area into independent triangles. For example an area with five sides can be triangulated as three triangles. Find the area of each triangle and add up each area to get the area. The formula to calculate the area of each triangle is this. If a,b,c are the sides of the triangle calculate its semi perimeter(s) that is s=(a+b+c)/2. The area of each triangle=square root of(sX(s-a)X(s-b)X(s-c))
I think this was what you are asking for.

I think one easy way to visualize an acre is that a football field is slightly more than an acre. Not counting the endzones, a football field is 300 ft long by 160 ft wide, or 48,000 sq ft. So, if you play football, this one is cake. :)

Actually, an acre is EXACTLY 43,560 square feet. That's pretty big.

To find the side of a perfect square, take sqrt(area)
sqrt(43560) =
208.71032557
