Calculate The Area Of A Rectangular Park A Step-by-Step Guide
Calculating the area of a rectangle is a fundamental concept in geometry with practical applications in various real-world scenarios. In this comprehensive guide, we will walk you through the process of finding the area of a rectangular park, given its length and width. Our specific example involves a park that is 30 3/5 meters long and 20 2/3 meters wide. We will break down the steps involved, from converting mixed fractions to improper fractions to performing the final multiplication. By the end of this article, you will have a clear understanding of how to solve similar problems and a solid grasp of the underlying principles.
Understanding the Basics of Rectangular Area
Before we dive into the specific problem, let's establish the foundational concept of the area of a rectangle. The area of a rectangle is the amount of two-dimensional space it occupies, measured in square units. Imagine covering the surface of the rectangle with tiny squares; the number of squares needed to cover the entire surface represents the area. The formula for calculating the area of a rectangle is straightforward: Area = Length × Width. This formula serves as the cornerstone for our calculations. Understanding this basic principle is crucial for solving more complex problems involving rectangular shapes and spaces.
To further illustrate, consider a simple rectangle with a length of 5 meters and a width of 3 meters. Using the formula, the area would be 5 meters × 3 meters = 15 square meters. This means you would need 15 squares, each measuring 1 meter by 1 meter, to completely cover the rectangle's surface. Now, let's move on to our park, which involves fractions, adding a layer of complexity to the calculation. But don't worry, we will tackle it step by step.
Step 1: Convert Mixed Fractions to Improper Fractions
The dimensions of our rectangular park are given in mixed fractions: 30 3/5 meters for the length and 20 2/3 meters for the width. To perform calculations, it's much easier to work with improper fractions. A mixed fraction consists of a whole number and a proper fraction (where the numerator is less than the denominator), while an improper fraction has a numerator that is greater than or equal to the denominator. Converting mixed fractions to improper fractions involves a simple process that we will now explore in detail.
To convert 30 3/5 to an improper fraction, we first multiply the whole number (30) by the denominator (5) and then add the numerator (3). This result becomes the new numerator, and the denominator remains the same. So, (30 × 5) + 3 = 150 + 3 = 153. Therefore, 30 3/5 is equivalent to 153/5. This transformation allows us to express the length as a single fractional value, making it easier to work with in calculations.
Similarly, we convert 20 2/3 to an improper fraction. Multiply the whole number (20) by the denominator (3) and add the numerator (2): (20 × 3) + 2 = 60 + 2 = 62. The denominator remains 3, so 20 2/3 is equivalent to 62/3. Now that we have both the length and the width expressed as improper fractions, we are ready to move on to the next step, which involves applying the area formula.
Step 2: Apply the Area Formula
Now that we have the length and width of the rectangular park expressed as improper fractions (153/5 meters and 62/3 meters, respectively), we can apply the area formula: Area = Length × Width. This is where the conversion to improper fractions becomes particularly useful, as it allows us to multiply the fractions directly.
To find the area, we multiply the two fractions: Area = (153/5) × (62/3). Multiplying fractions involves multiplying the numerators together and the denominators together. So, the new numerator will be 153 × 62, and the new denominator will be 5 × 3. Let's calculate these values.
153 multiplied by 62 is 9486. This gives us the new numerator. Next, we multiply the denominators: 5 × 3 = 15. This is our new denominator. Therefore, the area of the park, expressed as an improper fraction, is 9486/15 square meters. This is a large fraction, and while it accurately represents the area, it's often more practical to express it as a mixed fraction or a decimal. In the next step, we will simplify this fraction and convert it to a more understandable form.
Step 3: Simplify the Result
We have calculated the area of the rectangular park as 9486/15 square meters, an improper fraction. To make this result more understandable, we will simplify it and convert it to a mixed fraction. Simplifying a fraction involves reducing it to its lowest terms, while converting it to a mixed fraction means expressing it as a whole number and a proper fraction.
First, let's simplify the fraction 9486/15. To do this, we look for common factors between the numerator and the denominator. Both 9486 and 15 are divisible by 3. Dividing 9486 by 3 gives us 3162, and dividing 15 by 3 gives us 5. So, the simplified fraction is 3162/5 square meters. This simplified fraction is equivalent to 9486/15, but it is in a reduced form, making it easier to work with.
Next, we convert the improper fraction 3162/5 to a mixed fraction. To do this, we divide the numerator (3162) by the denominator (5). The quotient will be the whole number part of the mixed fraction, the remainder will be the numerator of the fractional part, and the denominator will remain the same. When we divide 3162 by 5, we get a quotient of 632 and a remainder of 2. Therefore, the mixed fraction is 632 2/5 square meters. This representation gives us a clearer sense of the size of the park's area, with 632 square meters being the whole number part and 2/5 of a square meter being the fractional part. In the final section, we'll summarize the steps and provide a concluding overview.
Step 4: Provide the Final Answer
Having gone through the step-by-step process, we have arrived at the final answer. The area of the rectangular park, which is 30 3/5 meters long and 20 2/3 meters wide, is 632 2/5 square meters. This result is obtained by converting the mixed fractions to improper fractions, multiplying them to find the area as an improper fraction, and then simplifying the result to a mixed fraction.
To recap, we first converted the length 30 3/5 meters to 153/5 meters and the width 20 2/3 meters to 62/3 meters. Then, we applied the area formula Area = Length × Width, which gave us (153/5) × (62/3) = 9486/15 square meters. Finally, we simplified this improper fraction to its lowest terms, 3162/5, and converted it to a mixed fraction, 632 2/5 square meters.
This detailed process illustrates how to calculate the area of a rectangle when the dimensions are given in mixed fractions. The key steps involve converting mixed fractions to improper fractions, applying the area formula, and simplifying the result. This skill is not only useful in mathematical contexts but also has practical applications in everyday life, such as calculating the area of rooms, gardens, or any other rectangular space.
