Thought-Process to Discover Knowledge
Welcome to the lessons that give firm foundation in measuring perimeter, area, and volume.
To measure a length, area, or volume one of the following methods is used.
• Measurement by Superimposition, Calculation and Equivalence
• Equivalence by infinitesimal pieces, and Cavalieri's Principle
Once the above is understood, the formula for perimeter, area, and volume of 2D and 3D shapes are provided.

Mensuration: 2D Shapes
The topics provide a simple overview of formulas for perimeter and area of
• square and rectangle
The derivation of these formulas are outlined for students to better understand and retain.
