Introduction

In this problem, we are tasked with finding the total length of eerkkil needed to create a rectangle with a length of 5½ centimeters and a breadth of 3½ centimeters. To solve this problem, we need to understand the concept of perimeter and how to calculate it.

Understanding Perimeter

The perimeter of a rectangle is the total length of its boundary. It is calculated by adding the lengths of all four sides of the rectangle. In this case, we have a rectangle with a length of 5½ centimeters and a breadth of 3½ centimeters.

Calculating the Perimeter

To calculate the perimeter, we need to add the lengths of all four sides of the rectangle. The formula for the perimeter of a rectangle is:

Perimeter = 2 × (length + breadth)

In this case, the length is 5½ centimeters and the breadth is 3½ centimeters. Plugging these values into the formula, we get:

Perimeter = 2 × (5½ + 3½) Perimeter = 2 × 9 Perimeter = 18

Calculating the Total Length of Eerkkil Needed

Since we are given that the total length of eerkkil needed is 5 cm. 3c cm, we can calculate the total length as 5 cm. 3½ cm. This is the same as the perimeter we calculated earlier.

Conclusion

In conclusion, the total length of eerkkil needed to create a rectangle with a length of 5½ centimeters and a breadth of 3½ centimeters is 18 centimeters. This is calculated by adding the lengths of all four sides of the rectangle using the formula for the perimeter of a rectangle.

Real-World Applications

Understanding how to calculate the perimeter of a rectangle is an important skill in many real-world applications. For example, in construction, architects need to calculate the perimeter of buildings to determine the amount of materials needed for the foundation, walls, and roof. In engineering, designers need to calculate the perimeter of machines and equipment to determine the amount of materials needed for the frame and other components.

Conclusion

Q: What is the perimeter of a rectangle?

A: The perimeter of a rectangle is the total length of its boundary. It is calculated by adding the lengths of all four sides of the rectangle.

Q: How do I calculate the perimeter of a rectangle?

A: To calculate the perimeter of a rectangle, you need to add the lengths of all four sides of the rectangle. The formula for the perimeter of a rectangle is:

Perimeter = 2 × (length + breadth)

Q: What is the length and breadth of a rectangle?

A: The length of a rectangle is the distance from one side of the rectangle to the other side, while the breadth of a rectangle is the distance from one side of the rectangle to the other side.

Q: How do I calculate the length and breadth of a rectangle?

A: The length and breadth of a rectangle can be calculated using a ruler or a measuring tape. Simply measure the distance from one side of the rectangle to the other side to get the length, and measure the distance from one side of the rectangle to the other side to get the breadth.

Q: What is the formula for the perimeter of a rectangle?

A: The formula for the perimeter of a rectangle is:

Perimeter = 2 × (length + breadth)

Q: Can I use a calculator to calculate the perimeter of a rectangle?

A: Yes, you can use a calculator to calculate the perimeter of a rectangle. Simply enter the length and breadth of the rectangle into the calculator and use the formula for the perimeter of a rectangle.

Q: What is the unit of measurement for the perimeter of a rectangle?

A: The unit of measurement for the perimeter of a rectangle is typically measured in centimeters (cm), meters (m), or inches (in).

Q: Can I calculate the perimeter of a rectangle with a non-standard shape?

A: Yes, you can calculate the perimeter of a rectangle with a non-standard shape. Simply measure the length and breadth of the rectangle and use the formula for the perimeter of a rectangle.

Q: What is the difference between the perimeter and the area of a rectangle?

A: The perimeter of a rectangle is the total length of its boundary, while the area of a rectangle is the amount of space inside the rectangle.

Q: Can I use the perimeter of a rectangle to calculate the area of a rectangle?

A: No, you cannot use the perimeter of a rectangle to calculate the area of a rectangle. You need to use the formula for the area of a rectangle, which is:

Area = length × breadth

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

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

Area = length × breadth
