【宮崎県過去問!!!】正方形上を移動する2点がつくる三角形の面積が36㎠になるときは何秒後？！【中3数学】

This video explains a problem from a past high school entrance exam in Miyazaki Prefecture, involving two points P and Q moving along the sides of a square and the area of ​​triangle APQ. How to find the distance traveled from the speeds of points P and Q Area of ​​triangle APQ when x = 3 and x = 6 The important concept of "case analysis" in moving point problems The equation y = 3x² when 0 ≤ x ≤ 4 The equation y = 12x when 4 ≤ x ≤ 6 and the concept of range Even those who struggle with moving point problems will find them easier to solve by drawing diagrams and organizing the information.
