The Students Of Class 6 Are Planning A Rectangular Garden For Their School.they Measure Boundary By A Rope And Found It Is 24 Meters Long. If They Want The Garden To Be 8 Meters Long, How Wide Can It Be?
Introduction
In mathematics, problems involving perimeter and area are essential for students to understand the relationship between the dimensions of a shape and its total boundary length. In this article, we will explore a real-life scenario where a group of students from class 6 are planning a rectangular garden for their school. They measure the boundary of the garden using a rope and find it to be 24 meters long. The students want the garden to be 8 meters long, but they are unsure about the width it can be. In this discussion, we will help the students find the solution to this problem.
Understanding the Problem
The students have measured the boundary of the garden using a rope and found it to be 24 meters long. This means that the perimeter of the garden is 24 meters. Since the garden is rectangular, we can use the formula for the perimeter of a rectangle, which is:
Perimeter = 2(length + width)
We are given that the length of the garden is 8 meters, and we need to find the width. Let's denote the width as 'w'. We can now substitute the values into the formula:
24 = 2(8 + w)
Solving the Equation
To solve for 'w', we need to isolate the variable. We can start by dividing both sides of the equation by 2:
12 = 8 + w
Next, we can subtract 8 from both sides of the equation to get:
4 = w
Therefore, the width of the garden can be 4 meters.
Conclusion
In this article, we helped a group of students from class 6 find the solution to a mathematical problem involving the perimeter and area of a rectangular garden. By using the formula for the perimeter of a rectangle and solving the equation, we were able to find the width of the garden, which is 4 meters. This problem is an excellent example of how mathematics can be applied to real-life scenarios, and we hope that this discussion has helped the students understand the concept better.

Introduction
In our previous article, we helped a group of students from class 6 find the solution to a mathematical problem involving the perimeter and area of a rectangular garden. The students measured the boundary of the garden using a rope and found it to be 24 meters long. They wanted the garden to be 8 meters long, but they were unsure about the width it could be. In this Q&A article, we will provide answers to some common questions that students may have while solving problems involving perimeter and area.
Q: What is the formula for the perimeter of a rectangle?
A: The formula for the perimeter of a rectangle is:
Perimeter = 2(length + width)
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. You can use the formula:
Perimeter = 2(length + width)
For example, if the length is 8 meters and the width is 4 meters, the perimeter would be:
Perimeter = 2(8 + 4) = 2(12) = 24 meters
Q: What is the difference between perimeter and area?
A: Perimeter is the total distance around the outside of a shape, while area is the amount of space inside the shape. For example, if you have a rectangular garden with a perimeter of 24 meters and an area of 32 square meters, the perimeter is the total distance around the garden, while the area is the amount of space inside the garden.
Q: How do I calculate the area of a rectangle?
A: To calculate the area of a rectangle, you need to multiply the length and width:
Area = length x width
For example, if the length is 8 meters and the width is 4 meters, the area would be:
Area = 8 x 4 = 32 square meters
Q: What is the relationship between perimeter and area?
A: The perimeter and area of a rectangle are related in that the perimeter is the total distance around the outside of the shape, while the area is the amount of space inside the shape. If you know the perimeter and one of the dimensions, you can use the formula to find the other dimension.
Q: How do I solve problems involving perimeter and area?
A: To solve problems involving perimeter and area, you need to follow these steps:
- Read the problem carefully and understand what is being asked.
- Use the formula for the perimeter or area of a rectangle to calculate the total boundary length or the amount of space inside the shape.
- Solve the equation by isolating the variable.
- Check your answer by plugging it back into the original equation.
Q: What are some real-world applications of perimeter and area?
A: Perimeter and area have many real-world applications, including:
- Architecture: Engineers need to calculate the perimeter of buildings to determine the amount of materials required for construction.
- Landscape design: Gardeners need to calculate the perimeter of gardens to determine the amount of fertilizer and water required.
- Urban planning: City planners need to calculate the perimeter of roads and buildings to determine the amount of space required for development.
