4.1 Definition of area and area calculation
|The area of a shape is a number that tells how many square units are needed
to cover the shape.
This is the basic concept of area.
The number of squares equals to the number of dots (dot-grids) approximately.
|When calculating the area complicated shapes, it is easier to count the number of dots than to count the number of squares.|
