The document is a presentation on the topic of mensuration, which is the branch of mathematics that deals with the measurement of geometric figures. It covers the origins of mensuration, its two main parts—plane mensuration and solid mensuration—and includes formulas for calculating the perimeter and area of different shapes. The author expresses gratitude to their math teacher for guidance and support in preparing the presentation.

2. Acknowledgement
I would like to express my special thanks to
my Math's teacher who gave me the golden
opportunity to do this wonderful presentation
on the topic ‘Mensuration’. This helped me in
doing a lot of research work and I came to
know about many things, I am really grateful
to the teacher for her constant guidance and
support.

4. Introduction
 The word “Mensuration” is derived from the
Greek word “Mensuration” meaning “to
measure” and refers to that branch of
mathematics and deals with the measurement
of geometric magnitudes, such as areas of
surfaces and volumes of solids. It is a practical
branch of mathematics.

5. Introduction
 The Mensuration took its birth in Egypt. Then
it was applied and expanded by great people
like Pythagoras, Euclid, Archimedes, Ptolemy
etc
 Mensuration is all about the process of
measurement. It is based on the use of
algebraic equations and geometric calculations
to provide measurement data regarding the
width, depth, and volume of a given object.

6. Quote-Unquote
 Listen to some famous quotes from famous
people about geometry.
• I think the universe is pure geometry-
basically, a beautiful shape twisting around
space-time.
– Antony Garret Lisi
• There is geometry in the humming of strings,
there is music in the spacing of spheres.
-Pythagoras

7. Parts
 Mensuration is divided into 2 parts:-
 1. Plane mensuration deals with the
measurement of solids, perimeters and areas
of plane figures like triangle, polygons etc.
 2. Solid mensuration deals with the
measurement of surfaces, areas and volumes
of solid figures like cube, cuboid, sphere,
cone, cylinder etc.

8. Plane Mensuration
In this presentation, I am gonna explain
you about plane mensuration which
means the measurement of solids,
perimeters and areas of plane figures
like triangle, polygons etc.
So lets begin with perimeter and area
and then circumference.

9. Perimeter and Area
TRIANGLE
 Perimeter of triangle= Sum of length of all sides
 Perimeter of an equivalent triangle= side*3
 Area of a triangle= ½ breadth*height

10. SQUARE
 Perimeter of square=4*s
 Area of square=s*s
Perimeter and Area

11. RECTANGLE
 Perimeter of rectangle=2*(length+breadth)
 Area of rectangle=length*breadth
Perimeter and Area

12. Circumference
CIRCUMFERENCE
  = 22/7 or 3.14159265358979323846
 = 2radius
 = diameter
