Introduction

In mathematics, scaling is a fundamental concept that helps us understand the relationship between different measurements and their representations. In this article, we will explore the concept of scaling and its application to a real-world problem involving a classroom floor. We will use the given information to calculate the area of the floor in a scale drawing.

Understanding the Problem

The problem states that the rectangular floor of a classroom is 28 feet in length and 36 feet in width. A scale drawing of the floor has a length of 14 inches. Our goal is to find the area of the floor in the scale drawing, expressed in square inches.

Scaling Down the Measurements

To solve this problem, we need to understand the concept of scaling. Scaling is a process of reducing or enlarging a measurement or a representation of an object. In this case, we are given the actual measurements of the classroom floor (28 feet in length and 36 feet in width) and the scale drawing of the floor (14 inches in length). We need to find the area of the floor in the scale drawing.

Calculating the Scale Factor

The scale factor is the ratio of the actual measurement to the scaled measurement. In this case, the scale factor is the ratio of the actual length (28 feet) to the scaled length (14 inches). We need to convert the actual length from feet to inches to make the units consistent.

1 foot = 12 inches

28 feet = 28 x 12 = 336 inches

Now, we can calculate the scale factor:

Scale factor = Actual length (inches) / Scaled length (inches) = 336 inches / 14 inches = 24

Finding the Area of the Floor in the Scale Drawing

Now that we have the scale factor, we can find the area of the floor in the scale drawing. The area of the floor in the scale drawing is proportional to the area of the actual floor. We can use the scale factor to find the area of the floor in the scale drawing.

Area of the actual floor = Length x Width = 28 feet x 36 feet = 1008 square feet

Now, we need to convert the area from square feet to square inches:

1 square foot = 12 x 12 = 144 square inches

Area of the actual floor (in square inches) = 1008 square feet x 144 square inches/square foot = 145152 square inches

Now, we can find the area of the floor in the scale drawing using the scale factor:

Area of the floor in the scale drawing = Area of the actual floor (in square inches) / Scale factor^2 = 145152 square inches / 24^2 = 145152 square inches / 576 = 252 square inches

Conclusion

In this article, we used the concept of scaling to find the area of the floor in a scale drawing. We started by understanding the problem and identifying the given information. We then calculated the scale factor and used it to find the area of the floor in the scale drawing. The final answer is 252 square inches.

Introduction

In our previous article, we explored the concept of scaling and its application to a real-world problem involving a classroom floor. We used the given information to calculate the area of the floor in a scale drawing. In this article, we will answer some frequently asked questions related to the problem.

Q&A

Q: What is scaling in mathematics?

A: Scaling is a process of reducing or enlarging a measurement or a representation of an object. It is a fundamental concept in mathematics that helps us understand the relationship between different measurements and their representations.

Q: How do I calculate the scale factor?

A: The scale factor is the ratio of the actual measurement to the scaled measurement. To calculate the scale factor, you need to divide the actual measurement by the scaled measurement.

Q: What is the difference between a scale drawing and a real-world object?

A: A scale drawing is a representation of an object that is smaller or larger than the actual object. It is a two-dimensional representation of the object, whereas a real-world object is a three-dimensional object.

Q: How do I convert measurements from one unit to another?

A: To convert measurements from one unit to another, you need to use conversion factors. For example, to convert feet to inches, you can use the conversion factor 1 foot = 12 inches.

Q: What is the area of the floor in the scale drawing?

A: The area of the floor in the scale drawing is proportional to the area of the actual floor. We can use the scale factor to find the area of the floor in the scale drawing.

Q: How do I find the area of the floor in the scale drawing?

A: To find the area of the floor in the scale drawing, you need to use the scale factor and the area of the actual floor. The formula is:

Area of the floor in the scale drawing = Area of the actual floor / Scale factor^2

Q: What is the final answer to the problem?

A: The final answer to the problem is 252 square inches.
