Introduction

In geometry, a rectangle is a quadrilateral with four right angles and opposite sides of equal length. The length and breadth of a rectangle are two of its most fundamental properties. In this article, we will explore the concept of length and breadth of a rectangle and how to find the ratio of the length to the breadth.

What is Length and Breadth of a Rectangle?

The length of a rectangle is the distance between two opposite sides, while the breadth is the distance between two adjacent sides. In other words, the length is the longer side, and the breadth is the shorter side. For example, if we have a rectangle with a length of 60 cm and a breadth of 35 cm, the length is 60 cm, and the breadth is 35 cm.

Finding the Ratio of Length to Breadth

To find the ratio of the length to the breadth of a rectangle, we simply divide the length by the breadth. In our example, the ratio of the length to the breadth is 60 cm / 35 cm. To simplify this ratio, we can divide both numbers by their greatest common divisor (GCD). In this case, the GCD of 60 and 35 is 5. Therefore, the simplified ratio is 12:7.

Calculating the Ratio

To calculate the ratio of the length to the breadth, we can use the following formula:

Ratio = Length / Breadth

In our example, the ratio is:

Ratio = 60 cm / 35 cm = 12/7

Simplifying the Ratio

To simplify the ratio, we can divide both numbers by their greatest common divisor (GCD). In this case, the GCD of 60 and 35 is 5. Therefore, the simplified ratio is:

Ratio = 12/7

Real-World Applications

The concept of length and breadth of a rectangle has many real-world applications. For example, in architecture, the length and breadth of a building are used to determine its size and shape. In engineering, the length and breadth of a bridge are used to determine its strength and stability. In everyday life, the length and breadth of a room are used to determine its size and layout.

Conclusion

In conclusion, the length and breadth of a rectangle are two of its most fundamental properties. The ratio of the length to the breadth is an important concept in geometry and has many real-world applications. By understanding the concept of length and breadth of a rectangle, we can better understand the world around us and make more informed decisions.

Example Problems

Problem 1

A rectangle has a length of 80 cm and a breadth of 40 cm. Find the ratio of the length to the breadth.

Solution

To find the ratio of the length to the breadth, we simply divide the length by the breadth.

Ratio = Length / Breadth = 80 cm / 40 cm = 2/1

Problem 2

A rectangle has a length of 90 cm and a breadth of 30 cm. Find the ratio of the length to the breadth.

Solution

To find the ratio of the length to the breadth, we simply divide the length by the breadth.

Ratio = Length / Breadth = 90 cm / 30 cm = 3/1
