Area Calculator : Useful Online Tool And Application

Area Calculator: Useful Online Tool and Application: The following are calculators for evaluating the area of ​​seven common shapes. The area of ​​more complex shapes can usually be obtained by breaking them into their overall plain shapes and aggregating their areas. This calculator is especially useful for estimating land area.

Area is a quantity that describes the size or extent of a two-dimensional figure or shape in a plane. It can be visualized as the amount of paint that will be needed to cover the surface, and is a two-dimensional replica of the one-dimensional length of the curve, and the three-dimensional volume of the cube. The standard unit of area in the International System of Units (SI) is square meters or m2. Below are the equations for some of the most common plain shapes and examples of how the area of ​​each is calculated.

A rectangle is a quadrilateral with four right angles. It is one of the simplest shapes, and its length and width only need to be known (or measured) to calculate its area. A quadrilateral is defined as a polygon with four edges and vertices. In the case of a rectangle, the length usually represents the two longest edges of the quadrilateral, while the width is smaller than the two edges. When the length and width of a rectangle are equal, the shape is a special case of a rectangle, called a square. The equation for calculating the area of ​​a rectangle is as follows:
