This example demonstrates rectangles with fractional side lengths and their properties, involving core math concepts like algebra, geometric construction, coordinate geometry, centroid, congruence, and integral calculus. It uses GeoGebra command object pic1 for construction, suitable for middle school and above learners to understand the characteristics and calculations of such rectangles.
AI Drawing Prompt Reference
Draw a rectangle with fractional side lengths, such as a length of 3/4 and a width of 2/3. Use coordinate geometry to set up a coordinate system, then draw the rectangle based on the fractional side lengths. Find and mark the centroid of the rectangle. Finally, calculate and verify the area and perimeter of the rectangle, and observe the position of the centroid.
