如何画图来表示数学常识 2 2 4?

Answer:

1. Draw a vertical line segment from the left to the right.
2. Mark the point where the line segment intersects the vertical axis at 2.
3. Draw a horizontal line segment from the point where the line segment intersects the vertical axis to the right.
4. Mark the point where the line segment intersects the horizontal axis at 4.

The resulting figure is a rectangle with the sides labeled 2, 2, and 4.
