# Area of diagonal generated triangles of rectangle are equal | Geometry | 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.

# Area of rectangles and the distributive property | Measurement | Pre-Algebra | Khan Academy

Use the distributive property to find area of rectangles

# 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).

# Understanding Rectangles: 2.G.2

## By Tenmarks Amazon

a rectangle is partitioned into rows and columns. The total number of partitioned pieces are identified.

# 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.
