Revision Notes Class 5 Mathematics Chapter 8 - How Many Squares?

2 Dimensional Figures / 2D Figures

  • A two-dimensional shape is a plane figure that can be drawn on a flat surface.

  • It has only two dimensions which are length and width. It has no thickness or depth

  • Example: Rectangle, Circle, Square etc


  • The area is the region enclosed by the boundary of a closed figure. 

  • Square units are used to measure area. 


  • Perimeter is the length that forms the boundary of an area (or) the total length of the boundary is called Perimeter.

  • If the figure is a triangle, square, or rectangle, the perimeter is the sum of the edge lengths.

  • We measure the perimeter of any figure in mm, cm, m, or km.




  • The measurement like length, width, and height of any object is known as dimensions. Different objects and shapes have different dimensions.

  • Based on dimension the area and perimeter will differ which means even if they look similar their areas and perimeters will be different because of dimensions.



Solved Example 1: Does your palm and length of your hand is smaller than your parents. Compare your hand with your parent and answer the question.

Ans: Yes, on comparing my hand with my father’s palm his palm is bigger than mine and also my father’s hand is longer than my hand.

Comparing hands

Comparing Hands

Counting Grids

  • To find the area and perimeter of any object we use the counting grids method. 

  • The area of a plane figure is the number of squares required to completely cover it and the perimeter of a plane figure is the number of squares required to cover the boundary of the figure.

  • Suppose we want to find the area of the below-given square. We can simply count the total number of small squares present in it because the area is nothing but space occupied by the shape of the object.

Counting grid

Counting Grid

  • Since it would be silly to always count all those squares to find the area and perimeter of any object. Also counting the squares will be difficult for the objects or shapes that big, that's why we use specific formulas for area and perimeter for specific objects which makes us easy to find.


  • A closed, two-dimensional shape with 4 equal sides is known as a Square. 

  • In Square all 4 sides are equal

  • Example of Square Shape Objects: Chessboard, a slice of bread, etc.

  • Formula of area of a Square = side × side

  • Formula of a Perimeter of a Square = 4 × length of a side



Solved Example 2: Find the perimeter and area of a square of side 10 cm.

Ans: We know that the perimeter of square = 4 × length of a side

Here given side= 10 cm

Therefore, perimeter = 4 × 10 cm = 40 cm

Now, area of the square = side × side sq. units

Therefore the area of square =10 × 10 = 121 cm2


  • A Closed two-dimensional shape in geometry, with 4 sides and 4 corners is known as a Rectangle. 

  • In Rectangle opposite sides of a rectangle have the same lengths and are parallel.

  • Example of Rectangle Shape Objects: Mobile,Television,Books etc.

  • Formula of area of rectangle =length × breadth

  • Formula of Perimeter of  Rectangle = 2 × length + 2 × breadth or 2(length + width).


Solved Example 3: Find the perimeter of a rectangle whose length and breadth are 10 cm and 12 cm, respectively.

Ans: Given: Length = 10 cm and Breadth = 12 cm

We know,

The perimeter of a rectangle = 2(length + width)

Substitute the value of length and width here,

Perimeter (P) = 2(10 + 12) cm

Thus p = 2 × 22 cm

Therefore, the perimeter of a rectangle = 44 cm.

Solved Example 4: Find the area of a rectangle with a length of 15 mm and a breadth of 9 mm.

Ans: Given 

The Length of a rectangle = 15 mm.

The breadth of a rectangle = 9 mm.

We know that the area of a rectangle = length × breadth 

Therefore the area of a rectangle = length × breadth

                                                            = 15 × 9 sq mm.

                                                            = 135 sq mm.

Thus the area of rectangle is 135


  • A triangle is a shape formed when three straight lines meet. All triangles have three sides and three corners (angles).

  • Examples of triangles in real life: Pyramids, Sailing Boats, Sandwich and pizza slices etc

  • Formula of area of triangle = \[ \frac{1}{2} \] × l × b where l = length and b = breadth.

  • Formula of Perimeter of  triangle = a + b + c where a, b, c are sides.

Perimeter of Triangle
Perimeter of Triangle

Solved Example 5: Find the area of a triangle with a base of 5 inches and a height of 8 inches.

Ans: Now let us find the area using the area of triangle formula:

We know that area of triangle = \[ \frac{1}{2} \] × l × b

Thus the area of triangle (A) = \[ \frac{1}{2} \] x 5 x 8

                                                A = \[ \frac{1}{2} \] x 40

Therefore, the area of the triangle (A) =20 m2

Solved Example 6: Anshu wants to find the perimeter of the pyramid toy which is in a triangle shape each side is 12 cm.

Ans: Since all three sides are equal in length, the triangle is an equilateral triangle.

i.e. a = b = c = 12 cm

Perimeter = a + b + c

Perimeter = 12 + 12 + 12

Perimeter = 36

Perimeter = 36 cm.

Relationship Between Area and Perimeter

  • Let us consider two rectangles A and B having the same perimeter as 18 units.

Relationship between area and perimeter of a rectangle

Relationship Between Area and Perimeter of a Rectangle

Observe the given rectangles here both of them have different areas i.e, Area of Rectangle A = 18 square units and Area of Rectangle B is 20 square units.

Relationship between area and perimeter

Relationship Between Area and Perimeter

Hence We Conclude That:

  • The two shapes having the same perimeter can have different areas. 

  • Similarly, two shapes having the same areas can have different perimeters.

Area of Irregular Shapes

  • Areas of irregular shapes can be found by counting the number of squares occupied by the irregular shape. 

  • As we don't have particular formulas for calculating the irregular shapes we use the counting square grids method.

  • Below are the measures that we consider to find the area of irregular shapes.

Area of irregular shapes

Area of Irregular Shapes

Solved Example 7:  Find The Area of below Figure:

Area of figure (A)

Ans: After coloring and counting the squares we observe that the total area of the figure will be (3+7+1) square units = 11 square units.

Area of figure (B)


  • Patterns are a set of numbers arranged in a sequence such that they are related to each other in a specific rule. 

  • Patterns are repeated arrangements of shapes, colours and numbers which are arranged while rotating it.

  • Example: tiles in our houses, checks on a shirt, mom’s saree with a design, a beautiful dress has a design pattern etc.
