Finding the Area of a Rectangle: Making Connections with Arrays

The video tutorial explains how to find the area of a rectangle by connecting the concept of area with arrays. It demonstrates that the area is the space inside a closed shape and can be calculated by counting the square units within it. The tutorial shows how arrays visually represent multiplication expressions, where one factor is the number of rows and the other is the number of dots in a row. By using examples, it illustrates how to calculate the area of rectangles using both unit squares and given dimensions, applying the distributive property to simplify multiplication. The video concludes by reinforcing the connection between area and arrays.

What is the area of a rectangle?

• The perimeter of the shape
