                                                                                      Mensuration     Learning Objectives

• Mensuration
• Perimeter of Geometrical Shapes
• Area of Geometrical Shapes

  Mensuration Mensuration is the branch of mathematics which deals with the measurement of lengths, area and volume of the plane and solid figures.   Perimeter of a plane figure: The distance all round a plane figure is called perimeter of the figure or the lengths of boundary of a plane figure is known as its perimeter                         \ Perimeter of the quadrilateral \[ABCD=AB+BC+CD+DA\]                                                 more...

• Data
• Statistics

  Data A collection of information in the form of numerical figures is called data. Raw data: Data obtained in the original form is called raw data. Tabulation of data: Arranging the data in a systematic form in the form of a table is known as tabulation of data.   Statistics The branch of mathematics which deals with the collection, presentation, analysis and interpretation of numerical data is called statistics.   Example A dice was thrown 30 times and the following outcomes were noted: 4, 3, 3, 2, more...

NUMBER SYSTEM   FUNDAMENTALS                     

•                   Digits: for representing any number we use ten symbols

0, 1, 2, 3,4,5,6,7,8,9 All the other numbers are written using 10 symbols. Example: more...

FRACTIONS AND DECIMALS   FUNDAMENTALS Natural numbers: All counting numbers are called natural numbers.

•                   It is denoted by N.
•                  \[N=\left\{ 1,2,3,4,\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \right\}\]

ALGEBRA   ALGEBRA The part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.   Introduction to Algebra

•                   Variable: A letter symbol which can take various numerical values is called variable or literal.

Example: more...

RATIO, PROPORTION AND UNITARY METHOD   RATIO The comparison of two quantity of same kind by division is called ratio.   Example: Ratio between Rs. 30 and Rs. 50, but there can be no ratio between Rs. 30 and 50 apples, form of ratio \[=x:y\] \[x\to \]antecedent \[y\to \]consequent
