Four measuring devices having metric calibrations. Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events.
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

The circle and the triangle are equal in area. Proposition one states: The area of any circle is equal to a right-angled triangle in which one of the sides about the right angle is equal to the radius, and the other to the circumference of the circle.
Śrīdhara wrote two extant mathematical treatises. The first, Pāṭīgaṇita, also called Bṛhat-Pāṭi ("Bigger Pāṭi") and Navaśatī ("Having 900"), extensively covered the practical mathematics of the time including arithmetic and mensuration (the part of geometry concerned with calculating sizes, lengths, areas, and volumes). [1]
This formula generalizes Heron's formula for the area of a triangle. A triangle may be regarded as a quadrilateral with one side of length zero. From this perspective, as d (or any one side) approaches zero, a cyclic quadrilateral converges into a cyclic triangle (all triangles are cyclic), and Brahmagupta's formula simplifies to Heron's formula.
The area formula for a triangle can be proven by cutting two copies of the triangle into pieces and rearranging them into a rectangle. In the Euclidean plane, area is defined by comparison with a square of side length , which has area 1. There are several ways to calculate the area of an arbitrary triangle.
