人们对基本图形的面积计算方式的了解多数局限于一种形式,而灵活性较强的题目所给的条件又不是既定公式的条件,在计算其面积时都还转化成既定公式的条件来进行,显得非常麻烦。本文收集了基本图形不同角度的面积公式,并理顺了它们之间的关系,在实际解题中得到很好应用,体现了“根据题目所给条件选择恰当的公式直接进行计算比较简便”的事实。 People’s understanding of the basic graphics area calculation mostly confined to a form, and the more flexible topic given the conditions are not the conditions of the established formula, in the calculation of its area are also transformed into the established formula conditions , It is very troublesome. This article collected the basic graphics of different angles of the area formula, and to straighten out the relationship between them, in the actual problem-solving has been well applied, reflects the conditions given by the subject to select the appropriate formula for direct calculation is relatively simple "fact.
