Answer: 1 acre = 43,560 ft²
One side of a 40-acre square is 1,320 feet.
It will be just under an acre. An acre contains 43,560 square feet. A closer dimension would be 210 by 210.
40 square rods = 1/4 acre.
20 by 20?
Answer: 1 acre = 43,560 ft²
If the lot has an area of 1 acre, and the shape is a square (acre is the area unit, not square acre). 1 acre = 43560 ft², so take the square root and get 208.71 ft side length.
One side of a 40-acre square is 1,320 feet.
You don't have to figger: a square acre has a perimeter of 208.7 fett on all four sides. But you can find the square root of the 43560 square feet inside an acre to get the perimeter measuremnets.
It will be just under an acre. An acre contains 43,560 square feet. A closer dimension would be 210 by 210.
One acre = 43,560 square feet (4047 square meters) The lot can be any shape, but an acre in the shape of a square would be about just short of 207 feet on each side.
There are 640 acres in a square mile, so there would be 16 forty-acre plots in one square mile.
About 40% of an acre.
The dimensions would be 40 feet by 40 feet.
An acre is a unit of land area equal to 43,560 square feet. Therefore, a square acre would have sides that are approximately 208.71 feet long.
1 acre = 43,560 square feet 0.4 acre = 17,424 square feet
As a unit of measure, an acre has no prescribed shape; any perimeter enclosing 43,560 square feet is an acre in size.
