Mensuration |
Introduction
The branch of arithmetic that is concerned with measurement of length, surface, and volume is called mensuration. Mensuration deals with so-called geometrical figures, such as squares, triangles, circles, cubes, spheres, and cylinders. Measurements of these figures are much used in surveying land, in building, plastering, and papering, in drawing and engineering, and in finding the capacity of boxes, tanks, and ships.
Types of Measurements
There major types of measurements are:
1. Perimeter: The length covered by the boundary of a two-dimensional figure.
2. Area(of a 2D figure): The space covered by a two-dimensional figure on a single plane.
3. Surface Area (of a 3D object): The measurement of the surface of an object.
4. Volume: The extent of space covered by a 3D object.
