在题干中给出新的数学知识(包括新的数学概念、定理、公式、法则和方法等),要求同学们通过阅读理解这些新的知识,并运用它们作进一步的推理,解决新的数学问题,这种问题称为“学习能力型”问题.下面选取有关分式的学习能力型考题加以说明.例1(2014年贺州中考)张华在一次数学活动中,利用“在面积一定的矩形中,正方形的周长最短”的结 In mathematics teaching, new mathematical knowledge (including new mathematical concepts, theorems, formulas, laws and methods, etc.) is given. Students are required to understand these new knowledge by reading them and use them for further reasoning to solve new mathematics Problem, this problem is called “learning ability type ” questions below to select the fractional learning ability type test questions to illustrate.Example 1 (2014 Hezhou senior high school entrance examination) Zhang Hua in a mathematical activity, the use of A certain rectangle, the shortest circumference of the square "knot
