Area

Quick Definition: The area is the amount of space enclosed by a shape. For a square, it's literally the amount of "area" inside the edges of the square. For a three-dimensional object, we use the term surface area to represent the area of one of the sides.

Example: The graphic below is a VERY simple example of the area of a rectangle. Multiplying the side lengths (3 times 4) gives us the area,12. To think of it visually, 12 squares that are each 1x1 would fit in this area.
