As an acre is a measure of area (a 2-dimensional object), a square acre is a 4-dimensional object; visualising 4-dimensional objects is not easy in our 3-dimensional space.
--------------------------------
Assuming you meant a square area which is 9 acres in size, then:
1 acre = 4840 sq yds
→ 9 acres = 9 × 4840 sq yds = 43560 sq yds
→ a square with an area of 9 acres has a side length of √43560 yards ≈ 208.71 yards (perimeter of approx 834.84 yards)
An area of 9 acres can have any shape you want. The smallest perimeter is when the 9 acres is circular in shape, in which case the perimeter is the circumference of the circle with area of 9 acres and is approx 739.86 yards long. Any other shape will have a perimeter that is longer than this.
Other examples are a rectangle 9 yards wide and 4840 yards long (perimeter 9699 yards);
a rectangle 198 yards wide (9 chains) by 220 yards long (1 furlong) (perimeter 836 yards).
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.
1 Acre = 43560 ft2 A square that is 208 feet 8½ inches (63.615 meters) on a side is just a little smaller than an acre.
Answer: 1 acre = 43,560 ft²
(1/2) acre = 21,780 square feet.
An acre contains 43,560 square feet. The conversion says that it would be 10,018.8 square feet.
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.
If you mean "area", there are 43,560 square feet in an acre. 10 x 43560 = 435,600 square feet.
There are 43,560 square feet in one acre.
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.
Any dimension that = 43,560 square feet. 208.75 x 208.75 = 43,576.56 sq ft.
