Parcel areas from dimensions and coordinates.
Geodesy
Triangle area from coordinates
S = |ΣXᵢYᵢ₊₁ − ΣYᵢXᵢ₊₁| / 2→GeodesyQuadrilateral area from coordinates
S = ½|Σ(XᵢYᵢ₊₁−YᵢXᵢ₊₁)|→GeodesyTrapezoidal parcel area
S = (a + b)h / 2→GeodesyArea in hectares
Sₕₐ = S / 10 000→GeodesyPolygon area from coordinate list
F = ½|Σ(xᵢyᵢ₊₁ − xᵢ₊₁yᵢ)|→GeodesyPolygon perimeter from coordinate list
P = Σ√(ΔX² + ΔY²)→
