In order to draw the square area formula, the following structure needs to be explored.
Move the bar and look as the rectangle is filled. How many small squares can fit in the side L of the square?
Change the measure of side (L) to 6. Move the bar and look as the rectangle is filled. How many little squares can fit in the side L of the square? [br]
What is the relationship between the number of squares (n) that fit in the square with the measure L on the side of the square?
In theory, the number of squares that fit in the square can be considered as the area of the square. Thus, write an equation that represents the area of a square of side L.
