One acre equals exactly 43,560 square feet. To convert an acreage, multiply the number of acres by 43,560. To convert square feet back to acres, divide by 43,560.
To visualize an area, the chart also gives the side length of a hypothetical square with that acreage. For example, a square containing one acre would be about 208.71 feet per side. Real lots do not have to be square.
The conversion follows NIST's acre and foot conversion factors.
Square-side lengths are rounded to the nearest tenth of a foot. The acre-to-square-foot calculations use 43,560 sq ft per acre.

For each row, the square-side figure is one possible way to picture the total area. A long rectangle or irregular parcel can contain the same number of acres while having very different dimensions.

For any parcel, multiply the acreage by 43,560 to find its area in square feet. To picture a square plot, take the square root of that area. The chart rounds those hypothetical square sides to the nearest tenth of a foot.
No. Acres measure area. A square, rectangle, or irregular parcel can contain the same acreage, and each shape has different boundary dimensions.
No. They are mathematical visualization examples, not surveyed parcel measurements, zoning guidance, or a recommended property layout.
