Irregular areas and volumes and mean values of waveforms
Published in John Bird, Bird's Engineering Mathematics, 2021
The area of a plot of land on a map is 400mm2. If the scale of the map is 1 to 50000, determine the true area of the land in hectares (1 hectare=104 m2). (3)
Ecological footprinting and other standards
Published in David Thorpe, ‘One Planet’ Cities, 2019
The biocapacity supply is a measure of the pollution land can absorb and the services and resources it can provide to the population under investigation. The demand is a factor of this given population level and its consumption level, which is determined by its use of cropland, forests, grazing land and fishing grounds for providing resources and absorbing carbon dioxide from burning fossil fuels. The result can be an average of hectares per person (or nation), as if it were distributed equally between everyone (in the world or a given country) and as if all land were equal in what it could provide. A hectare is 2.47 acres or 10,000 square metres (m2) or 0.01 km2.
The Content of the Site Plan

Each tract, lot, and structure on the site plan, as well as many features will be identified by area. A square measuring one acre is about 208 by 208 feet (43,560 square feet). A square mile is 640 acres. The metric system is used rarely in review of site plans, but it is found increasingly in scientific applications such as wildlife surveys, forestry management plans, and hydrogeology. Under the metric system, one hectare (ha) equals 2.47 acres (1 acre = 0.405 ha) and is equivalent to 10,000 square meters. A square meter equals 10.76 square feet.

Within the scope of the study, it is aimed to determine the most suitable places for airport site selection. In this context, the 16 criteria used to determine the most suitable place and the weights determined by the decision-makers were brought together in raster format. The resulting map showing the most suitable places was obtained. Nine regions were identified as the most suitable area (Figures 9, Figures 10, Figures 11, Figures 12, Figures 13, Figures 14, Figures 15, Figures 16, 17). The results were examined one by one, and the following conclusions were reached: Area A is located in Guzelyali and Eskikizilcakese neighbourhoods of Unye district of Ordu province. It is 622 hectares. Its distance from the city centre is 51.5 km.Area B is located in Yeniergen and Ergenturk neighbourhoods of Kumru district of Ordu province. It is 819 hectares. Its distance from the city centre is 73.4 km.Area C is located in Cavdar village of Akkus district of Ordu province. It is 1807 hectares. Its distance from the city centre is 130 km.Area D is near the Seferli neighbourhood of Akkus district of Ordu province. It is 1677 hectares. Its distance from the city centre is 133 km.Area E is located in the Safe neighbourhood of Mesudiye district of Ordu province. It is 3048 hectares. The distance to the city centre is 122 km.Area F is located in the Balikli neighbourhood of the Mesudiye district of Ordu. It is 1720 hectares. The distance to the city centre is 109 km.Area G is located in Ordu province Altinordu district, Emenkoy, Osmaniye and Altinca neighbourhoods. It is 4229 hectares. Its distance to the city centre is 23.2 km.Area H is located in Derekoy and Ortacokdegirmen neighbourhoods of Unye district of Ordu province. It is 1450 hectares. The distance to the city centre is 87.9 km.Area J is located in Salman and Seferli neighbourhoods of Akkus district of Ordu province. It is 1369 hectares. The distance to the city centre is 130 km.
