INTRODUCTION

• Mensuration is the branch of geometry which deals with the measurement of area, length or volume. It is also the act or process of measuring.

• The Mensuration took its birth in Egypt. Then it was applied and expanded by great people like Pythagoras, Euclid, Archimedes, Ptolemy etc and further developed by Halley, Bernoulli's, Euler, Newton etc.

Important Terms

• Solid: A body or geometric figure having three dimensions.

Important Terms• Surface Area: The total area of the surface

of the three dimensional figure.

Important Terms• Perimeter: The continuous line forming the

boundary of a geometrical figure.

Important Terms• Volume: The total space occupied by an

object or the space inside a container.

Figures• Plain figures: Plain figures are all about flat

2-dimensional shapes such as circle, rectangle, etc.

• Solid Figures: Solid Geometry consists of all 3-dimensional figures like cubes, spheres, etc.

Measuring Plain Figures SQUARE :- All sides are equal in a square, therefore,

No. of sides = 4 Perimeter = 4 X Side Area of Square: Side X Side

Side

Example

Measuring Plain Figures TRIANGLE:-• Area of Triangle: ½ X base X height

• Perimeter of Triangle: Side +Side +Side
