Mensuration is a branch of mathematics that deals with the measurement of geometric figures and their parameters like length, volume, shape, surface area, lateral surface area, etc. . It is the process of measurement based on algebraic equations and mathematical formulas. Mensuration is also defined as the study of the measurement of geometric magnitudes such as length. The branch of mathematics dealing with the determination of length, area, or volume is also referred to as mensuration. Key points to note about mensuration include:

• It is a branch of mathematics that studies the measurement of 2D and 3D figures on parameters like length, volume, shape, surface area, etc. .
• Mensuration deals with the measurement of plane shapes and solid shapes.
• It involves the calculation of various parameters of shapes like the perimeter, area, volume, etc. .
• Mensuration is used in various fields such as architecture, engineering, physics, and many more.

In summary, mensuration is a branch of mathematics that deals with the measurement of geometric figures and their parameters. It involves the calculation of various parameters of shapes like the perimeter, area, volume, etc. and is used in various fields such as architecture, engineering, and physics.
