Area of rectangles and rectangular shapes. Concrete case of the distributive property (3.MD.7.c)
By Math Mammoth
Area of rectangles can be found by multiplication. In my example rectangle, we count the rows and columns, and then write a multiplication to find the area (5 x 3 = 15 squares).
Area of rectangles and rectangular shapes. Concrete case of the distributive property (3.MD.7.c)
By Math Mammoth
the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c.
