Math Grade 3 Quiz Area of a Rectangle using Tiling and the Distributive Property – 3.MD.C.7.C

This standard delves into the understanding of the area of a rectangle by using a tangible approach called tiling. Specifically, if one of the side lengths of the rectangle can be broken into two separate lengths (b and c), then the area of the rectangle is the sum of two smaller rectangles: one with side lengths a and b and the other with side lengths a and c. This concept aids in visualizing the distributive property of multiplication over addition.
