Area of a shape is a two dimensional quantity. The term “area” refers to the space inside the boundary or perimeter of a closed shape. The geometry of such a shape contains at least three sides joined together to form a boundary. Symbolic representation of such space in mathematics refers to the “area” formula.
The area of any shape is the number of unit squares that can fit into it. The grid is made up of many squares of sides 1 unit by 1 unit. The area of each of these squares is 1 square unit. Hence, each square is known as a unit square. Look at the figure shown below. Let us find the area of the shape drawn in the grid.
Area plays an important role in modern mathematics. In addition to its obvious importance in geometry and calculus, area is related to the definition of determinants in linear algebra, and is a basic property of surfaces in differential geometry.

Area Definition (Illustrated Mathematics Dictionary) Definition of. Area. more ... The size of a surface. These shapes all have the same area of 9: Examples: The amount of space. • inside the boundary of a flat (2D) object such as a circle or square, or. • on the surface of a solid (3D) object such as a sphere or cube.
Jan 11, 2023 · Area definition in math. In geometry, area is the amount of space a flat shape, like a polygon, circle or ellipse, takes up on a plane. The area of a shape is always measured in square units. Once you know how square units relate to area, you can find the area of just about any two-dimensional shape.

The concepts of area and perimeter are the basis for understanding Euclidean geometry and calculating the volume of solid shapes in 3-dimensional space such as cones, prism, sphere, and cylinder. Also, we use these formulas for calculating the area and perimeter for quadrilaterals and polygons comprising of sides and curves.
Area. Area is the amount of space covered by a two-dimensional figure in a plane. It is the two-dimensional counterpart to length in one dimension, and volume in three dimensions. Area in geometry. The area covered by a shape can be calculated from its 1-dimensional parameters, such as the length and width of a rectangle.
