It is required to you
- Knowledge of geometry.
Instruction
1. Let the squared ground with the parties 42 and 21 meter be given. It is necessary to calculate its area. For this purpose use a formula of the area of a rectangle where the area of a rectangle is equal to the work of lengths of its parties. That is area of S = 42*21 = 882 square meters.
2. So, land area is equal 882 square meters. Follows from definition of a hundred part that it is equal to the site of hundred square meters. To find out how many hundred parts in the site of 882 square meters need to be divided 882 into 100 and to receive the answer in hundred parts. That is 882/100 = 8.82 hundred parts or that one and too, 8.82 macaws.
3. If land area is more than 100 hundred parts, then one more unit of measure - hectare is entered. One hectare is equal to 100 hundred parts or 100 ares. That is, if land area is 20000 square meters, then it is equal to 200 hundred parts or 2 hectares.
