Introduction

In geometry, a hexagon is a polygon with six sides. It is a fundamental shape in mathematics, and its properties have been studied extensively. In this article, we will explore the problem of finding the area of a hexagon using two different methods. The hexagon in question is MNOPQR, with each side measuring 5 cm. Aman and Ridhima have divided the hexagon in two different ways, and we will use both methods to find the area of the hexagon.

Aman's Method

Aman's method involves dividing the hexagon into six equilateral triangles. Each triangle has a side length of 5 cm, and the area of an equilateral triangle can be calculated using the formula:

Area = (√3 / 4) × side^2

Using this formula, we can calculate the area of each triangle:

Area = (√3 / 4) × 5^2 = (√3 / 4) × 25 = (1.732 / 4) × 25 = 10.825 cm^2

Since the hexagon is divided into six equilateral triangles, the total area of the hexagon can be calculated by multiplying the area of one triangle by 6:

Total Area = 6 × 10.825 cm^2 = 64.95 cm^2

Ridhima's Method

Ridhima's method involves dividing the hexagon into two congruent trapezoids. Each trapezoid has a base length of 10 cm and a height of 8 cm. The area of a trapezoid can be calculated using the formula:

Area = (1/2) × (base1 + base2) × height

In this case, the bases of the trapezoid are 10 cm and 5 cm, and the height is 8 cm. Plugging these values into the formula, we get:

Area = (1/2) × (10 + 5) × 8 = (1/2) × 15 × 8 = 60 cm^2

Since the hexagon is divided into two congruent trapezoids, the total area of the hexagon can be calculated by multiplying the area of one trapezoid by 2:

Total Area = 2 × 60 cm^2 = 120 cm^2

Comparison of Results

We have used two different methods to find the area of the hexagon. Aman's method involves dividing the hexagon into six equilateral triangles, while Ridhima's method involves dividing the hexagon into two congruent trapezoids. The results of the two methods are:

Aman's Method: 64.95 cm^2 Ridhima's Method: 120 cm^2

It is clear that the results of the two methods are different. However, we can use the formula for the area of a hexagon to verify which method is correct.

Formula for the Area of a Hexagon

The formula for the area of a hexagon is:

Area = (3√3 / 2) × side^2

Using this formula, we can calculate the area of the hexagon:

Area = (3√3 / 2) × 5^2 = (3 × 1.732 / 2) × 25 = 2.598 × 25 = 64.95 cm^2

This result matches the result obtained using Aman's method. Therefore, we can conclude that Aman's method is correct.

Conclusion

In this article, we have used two different methods to find the area of a hexagon. Aman's method involves dividing the hexagon into six equilateral triangles, while Ridhima's method involves dividing the hexagon into two congruent trapezoids. The results of the two methods are different, but the formula for the area of a hexagon verifies that Aman's method is correct. We have also used the formula for the area of a hexagon to calculate the area of the hexagon, which matches the result obtained using Aman's method.

Introduction

In our previous article, we explored the problem of finding the area of a hexagon using two different methods. Aman's method involved dividing the hexagon into six equilateral triangles, while Ridhima's method involved dividing the hexagon into two congruent trapezoids. We used the formula for the area of a hexagon to verify that Aman's method was correct. In this article, we will answer some frequently asked questions about finding the area of a hexagon.

Q: What is the formula for the area of a hexagon?

A: The formula for the area of a hexagon is:

Area = (3√3 / 2) × side^2

Q: How do I find the area of a hexagon if I don't know the side length?

A: If you don't know the side length of the hexagon, you can use the formula for the area of a hexagon in terms of the apothem (the distance from the center of the hexagon to one of its vertices). The formula is:

Area = (3√3 / 2) × apothem^2

Q: Can I use other methods to find the area of a hexagon?

A: Yes, there are several other methods you can use to find the area of a hexagon. Some of these methods include:

Dividing the hexagon into six equilateral triangles and using the formula for the area of a triangle
Dividing the hexagon into two congruent trapezoids and using the formula for the area of a trapezoid
Using the formula for the area of a hexagon in terms of the apothem
Using the formula for the area of a hexagon in terms of the side length and the height of the hexagon

Q: How do I know which method to use?

A: The method you choose will depend on the information you have available and the level of accuracy you need. If you have the side length of the hexagon, Aman's method (dividing the hexagon into six equilateral triangles) is a good choice. If you have the apothem of the hexagon, you can use the formula for the area of a hexagon in terms of the apothem.

Q: Can I use the formula for the area of a hexagon to find the area of other polygons?

A: Yes, the formula for the area of a hexagon can be used to find the area of other polygons, such as triangles, quadrilaterals, and pentagons. However, you will need to use a different formula for each type of polygon.

Q: How do I apply the concept of area to real-world problems?

A: The concept of area is used in many real-world problems, such as:

Finding the area of a room or a building
Calculating the cost of materials for a construction project
Determining the area of a plot of land
Finding the area of a piece of art or a design

Q: What are some common mistakes to avoid when finding the area of a hexagon?

A: Some common mistakes to avoid when finding the area of a hexagon include:

Not using the correct formula for the area of a hexagon
Not having the correct side length or apothem of the hexagon
Not using the correct method for the problem at hand
Not checking your work for errors

Q: How can I practice finding the area of a hexagon?
