Introduction
Dilation is a fundamental concept in mathematics that involves changing the size of a shape or a figure. It is an essential topic in geometry, and understanding dilation and scale factors is crucial for solving various mathematical problems. In this article, we will explore the concept of dilation and scale factors, and we will use a real-world example to demonstrate how to apply these concepts to solve a problem.
What is Dilation?
Dilation is a transformation that changes the size of a shape or a figure. It involves scaling the shape up or down by a certain factor, known as the scale factor. The scale factor is a ratio that compares the size of the original shape to the size of the transformed shape.
Understanding Scale Factors
A scale factor is a ratio that compares the size of the original shape to the size of the transformed shape. It is usually represented by a number or a fraction. For example, if a shape is dilated by a scale factor of 2, it means that the size of the shape is doubled.
Applying Dilation and Scale Factors to Real-World Problems
Now that we have a good understanding of dilation and scale factors, let's apply these concepts to a real-world problem. Ricardo has a square hot tub, and he wants to build a square pool next to it that is a dilation of the hot tub using a scale factor of 5. If the pool is to be 24 ft on each side, what is the length of one side of the hot tub?
Step 1: Understand the Problem
The problem states that Ricardo wants to build a square pool next to his square hot tub. The pool is to be a dilation of the hot tub using a scale factor of 5. This means that the size of the pool will be 5 times the size of the hot tub.
Step 2: Identify the Given Information
The given information is:
- The pool is to be 24 ft on each side.
- The scale factor is 5.
Step 3: Apply the Scale Factor
To find the length of one side of the hot tub, we need to apply the scale factor. Since the scale factor is 5, we can set up a proportion to relate the size of the pool to the size of the hot tub.
Let x be the length of one side of the hot tub. Then, the length of one side of the pool is 5x.
We know that the length of one side of the pool is 24 ft, so we can set up the following equation:
5x = 24
Step 4: Solve for x
To solve for x, we can divide both sides of the equation by 5:
x = 24/5
x = 4.8
Conclusion
In this article, we explored the concept of dilation and scale factors in mathematics. We used a real-world example to demonstrate how to apply these concepts to solve a problem. Ricardo has a square hot tub, and he wants to build a square pool next to it that is a dilation of the hot tub using a scale factor of 5. If the pool is to be 24 ft on each side, the length of one side of the hot tub is 4.8 ft.
