MATHS WORKSHEETS

  Area:  Area is the region enclosed in a figure.  Different shapes have different formula to find the area.  Area is refer to 2-dimensional shapes. So while finding the area just multiply the two sides of the given shape. Area of a square = length x length  Area of a rectangle = length x breadth  Area of a parallelogram = base x height  Area of a triangle = 1/2 x base x height  Point to remember: Height is perpendicular to its base    Example 1:  If we have a square of side 5 cm. What will be the area of a square?  Solution:  As we know that a square has 4 equal sides and if one side is of 5 cm then all the 4 sides will be of 5 cm.    Area = length x length                 = 5 cm x 5 cm            = 25 cm sq.  Example 2:  If we have a rectangle of length 6 cm and breadth 4 cm. What will be the area of a rectangle?  Solution:  As we know that a rectangle has 4 sides. Two opposite equal and parallel sides.  Area = length x breadth              = 6 cm x 4 cm            = 24 cm sq. 

  Perimeter:  Perimeter is the distance around the figure.  Commonly, Perimeter is the sum of all sides.  Example 1: If we have a square of side 5 cm. What will be the perimeter of a square?  Solution: As we know that a square has 4 equal sides and if one side is of 5 cm then all the 4 sides will be of 5 cm.  Note: For square, Perimeter = 4 x length    Perimeter = sum of all sides                        = 5 cm + 5 cm + 5 cm + 5 cm                   = 20 cm  Example 2:  If we have a rectangle of length 6 cm and breadth 4 cm. What will be the perimeter of a rectangle?  Solution:  As we know that a rectangle has 4 sides. Two opposite equal and parallel sides.  Note:  For rectangle, Perimeter = 2 (length + breadth) = 2 L + 2 B                                               Perimeter = sum of all sides                        = 6 cm + 6 cm + 4 cm +  4 cm                   = 20 cm 

 Index Notation:  To write a number in power from the standard is known as Index Notation.  For Example:    Note: To write the index notation of any number we use the method called Prime Factorization . This method gives us the prime factors as a product of a number. At the end, we can write it as index notation  What is 21056 in index form? Point to Remember: We can only use prime numbers in prime factorization  

Word Percent is originated from a Latin word.  Per cent means out of every hundred. (  /100) we know that, a percent can be written as a fraction and a decimal.  For solving this kind of problems. Lets see some steps:  Step 1: Change percentage into fraction  Step 2: Replace "of" with multiplication symbol (x) Step 3: Multiply numerator with a whole number  Step 4: Divide a number that is a numerator by a number that is in the denominator
