An acre is a measure of area and has two dimensions;640 acres by 640 acres is 409600 acres2 which has four dimensions.Methinks you do not mean a property that is 640 acres by 640 acres.Getting back to just 640 acres (and forgetting the "by 640 acres") as long as the shape has an area of 640 acres it doesn't matter what shape it is.The shape with an area of 640 acres with least perimeter is a circle:area = π x radius2⇒ radius = √(area/π)circumference = 2 x π x radius= 2 x π x √(area/π)= 2 x √(area x π)= 2 x √(640 x 4840 sq yds x π)≈ 6239 ydsAny other shape will have a longer perimeter - it can have any value greater than approx 6239 yards, examples a rectangle with sides:2 yds and 1548800 yds will have an area of 640 acres and a perimeter of 3097604 yds;1 yd and 3097600 yds will have an area of 640 acres and a perimeter of 6195202 yds.
18 ft = 6 yds 12 ft = 4 yds 6 yds x 4 yds = 24 yds2
One acre equals 43,560 square feet. 100' X 100' equals 10,000 square feet and is approximately .229 of an acre.
1 acre = 4840 sq yds → 0.31 scre = 0.31 x 4840 sq yds = 1500.4 sq yds → a square with side length √(1500.4 sq yds) ≈ 38.735 yds ≈ 38 yds 2 ft, 2.5 in
100' x 100' is 0.0229568 acres.
3.347 acres.
Equals 0.75528007 acres
100' x 900' equals 2.07 acres.
1 acre = 4840 sq yds 15 acres = 15 x 4840 sq yds = 72600 sq yds

It can be any length and width you want as long as length x width = 0.26 acres in area, For example it could be:1 yard wide by 1258.4 yards long since 1 yd x 1258.4 yds = 1258.4 sq yds = 0.26 acres1 foot wide by 11325.6 feet long since 1 ft x 11325.6 ft = 11325.6 sq ft = 0.26 acresapprox 11.22 yds wide by approx 112.16 yds long since 11.22 yds x 112.16 yds ~= 1258.4 sq yds = 0.26 acres35.47 yds wide by approx 35.48 yds long since 35.47 yds x 35.48 yds ~= 1258.4 sq yds = 0.26 acres

100' x 100' = 10,000 ft² = 0.229568411 acres.
80' x 100' = 0.184 acres.
About 2.06 acres for 100' x 900'
