One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3). There has been two definitions of the acre-foot (differing by about 0.0006%), using either the international foot (0.3048 m) or a U.S. survey foot (exactly 1200 / 3937 meters since
One of the reasons for creating sections of 640 acres (260 ha) was the ease of dividing into halves and quarters while still maintaining a whole number of acres. A section can be halved seven times in this way, down to a 5-acre (2 ha) parcel, or half of a quarter-quarter-quarter section—an easily surveyed 50-square- chain (2 ha) area.
For example, if a lot must adhere to a 0.1 FAR, then the total area of all floors in all buildings on the lot must be no more than one-tenth the area of the parcel itself. In other words, if the lot was 10,000 sq. ft, then the total floor area of all floors in all buildings must not exceed 1,000 sq. ft.
In United States agricultural policy, Farm acreage base referred to the total of the crop acreage bases (wheat, feed grains, cotton, and rice) for a farm for a year, the average acreage planted to soybeans and other non-program crops, and the average acreage devoted to conserving uses (excluding Acreage Reduction Program land) The 1996 farm bill (P.L. 104-127) and the 2002 farm bill (P.L. 107 ...
A lot has defined boundaries (or borders) which are documented somewhere, but the boundaries need not be shown on the land itself. Most lots are small enough to be mapped as if they are flat, in spite of the curvature of the Earth. A characteristic of the size of a lot is its area. The area is typically determined as if the land is flat and ...
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.
