The area calculation for a two-dimensional shape is the first step to interpret the volume of a three-dimensional object such as cone, cylinder, ball, and cube.ġ. The rescaled version of the area for a given place is useful in designing knowledge tools such as globes and geophysical maps. The application field of area formula is in architecture, land surveying, and map designing. Let’s take an example, the area of a square with side length 8 cm is: ![]() The resultant unit is the product of the units of the given lengths. The unit of measurement for the area is always the square of the unit in which lengths are given. The “textured” region represents the area of the shape Opposite sides are equal and parallelOpposite angles are equal Opposite sides are equal and parallelEach angle is 90 degree The length between the center “o” to the point on the circumference is the radius “r”Īll sides are equalEach angle is 90 degreeĪll sides are equalOpposite sides are parallelOpposite angles are equal In the following pictures, the shaded region denotes the area for the respective shapes. ![]() We calculate the area for different shapes using math formulas. The area of a shape is the “space enclosed within the perimeter or the boundary” of the given shape. ![]() Mirrors of different shapes with sides and curves. Shapes with bounded curves don’t have sides but have the circumference. Geometric shapes are the figures with a set of points connected by lines resulting in a closed figure.įor example, triangle, square, rectangle and quadrilateral are shapes with 3 and 4 points connected by lines.
