Mensuration Formulas Class 6

Mensuration formulas for class 6 are used to calculate the various parameters of shapes like the area, perimeter or volume. They may seem to look complicated and difficult to use, especially for younger students. However, regular practice and the correct usage helps to ease out the process of memorizing them. This article has a summarized list of important mensuration formulas for class 6 and some handy tips to remember them that will help students learn them easily.

List of Class 6 Mensuration Formulas

Here is a summarized list of a few Class 6 mensuration formulas.

• The perimeter is the overall distance around the given shape's periphery.
• The area tells how much space a given shape occupies in space.
• Perimeter of a Rectangle = 2 × (Length + Breadth)
• Perimeter of a Square = 4 × Length Of Its Side
• Perimeter of an Equilateral Triangle = 3 × Length of a Side
• Area of A Rectangle = Length × Breadth
• Area of A Square = Side × Side

Applications of Class 6 Mensuration Formulas

The idea of calculating the area and perimeter of shapes is widely used in our everyday life as given in the following examples.

• If one needs to find the amount of fencing required around the edge of a garden, it can be found out by calculating the perimeter of the field.
• The area formula can be helpful in finding the area of a plot of land if it needs to be divided into equal parts.
• If one needs to find the number of tiles required for flooring, or the number of bricks required to build a wall, these formulas come handy in finding out the exact quantities needed for construction.

Tips to Memorize Mensuration Formulas Class 6

Mensuration formulas class 6 are the introductory formulas to understand the concept of dimensions in the real world. The following tips would help the students to learn these formulas without any hassle.

• Start by physically writing down the formula and its explanation in complete sentences as this makes it easier for the brain to process what it is reading.
• The students must go through the solved examples in their textbooks and try to practice them on their own. This will help them in getting the logic behind the relevant formula and its usage in a particular context. Once done with the solved examples, they should move on to the exercise questions. A variety of questions would include different formulas which could be helpful in revising each formula multiple times.
• The students can also download the formula images from the internet and set it as wallpaper on their desktops and mobile. In this way, whenever they see it, they will be prompted to revise them. 

Mensuration Formulas for Class 6 Examples

Example 1: Calculate the perimeter of a rectangle whose length and breadth are 35 cm and 15 cm respectively.

Solution: Given , Length = 35 cm and Breadth = 15 cm

The formula for Perimeter of the rectangle = 2 × (length + breadth) 

Substituting the values of length and breadth, we get,

Perimeter of the rectangle = 2 × (35 + 15) = 2 × 50 = 100 cm.

Example 2: What will be the cost of fencing a rectangular garden of length 220 m and breadth 100 m at the rate of Rs. 12 per metre? 

Solution: Length of the rectangular garden = 250 m

Breadth of the rectangular garden = 175 m 

To calculate the cost of fencing we need to find out the perimeter. 

Perimeter of the rectangle = 2 × (length + breadth) = 2 × (220 + 100) = 2 × (320) = 640 m 

Therefore, the total cost of fencing the garden = 12 × 640 = Rs. 7680

Example 3 : What is the distance travelled by Misha if she runs four rounds of a square plot of land with side 60 m?

Solution : Perimeter of the square plot of land = 4 × length of a side = 4 × 60 = 240 m 

Distance covered in one round = 240 m 

Therefore, distance covered in four rounds = 4 × 240 = 960 m
