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.

          Area of diagonal generated triangles of rectangle are equal | Geometry | Khan Academy


          By Khan Academy

          In this video, Mr. Khan draws a box and two intersecting lines that produce several triangles. Mr. Khan proves that the area of these diagonal-generated triangles of the rectangle are equal. He goes over the formula for finding the area of a triangle. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The screen gets busy (and dark)--the viewer may want to open to 'full screen' to see everything. The sound is a little low
