  1. Group 1 question:
    For the diagram on the right, would be good to pen down the sum of the areas of the 4 rectangles.

    Group 2 question:
    The diagram looks ok.
    However, you explanation in the lower right portion seems incomplete.
    I presume what's written on the left hand side is your working for distributive law :)
