Area is the size of a surface! These shapes all have the same area of 9: It helps to imagine how much paint would cover the shape.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area.

In mathematics, the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number. There are several well-known formulas for the areas …

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure.

Area is a two-dimensional quantity that represents the space inside the boundary or perimeter of a shape. Different shapes have different formulas to calculate their areas.

Many geometric figures are made up of two or more common figures, and their areas can be calculated using a combination of the area formulas above. These types of geometric figures …
