Build rectangles on a grid and connect width × height with area.

🎮 Try It
Drag the red width and blue height handles, and compare grids up to 10 and 12. In Partition mode, split the same rectangle vertically and horizontally, then move the partition line and open the calculation panels.

🎯 Your Mission
Build a rectangle with area 24 in two different ways. Choose one rectangle, split it into two parts, and show that the two partial areas still make 24.

🌍 Real-World Connection
Floor plans divide rooms into rectangles so their areas can be calculated and added.
