1 â 10 are usually best written as full words (one, two , three etc). 11+ would be written as numbers. Thereâs no strict rule on this: 11-20 may often also be written as words, but 21+ would almost always be put down as numbers. Make sure youâre consistent over this: donât sometimes write twenty but in other places 20.
Lot area is the area of a parcel of land. Floor area is the sum of a buildingâs usable floor area that is constructed. Their relationship is defined by local Zoning Codes, which usually limit the % of lot coverage (also known as building coverage), the Floor to Area Ratio (F.A.R.), the maximum building height, mandatory setbacks from each side of the parcel etc.
In human geography, a catchment area is the area from which a city, service or institution attracts a population that use their services. For example, a school catchment area is the geographic area from which students are eligible to attend a local school. Supermarkets, on the other hand, have a much lower density, with catchment areas of several neighborhoods (or several villages in rural areas). 2  This principle, similar to the central place theory, makes catchment areas an important area of study for geographers, economists, and urban planners.
