This comprehensive report delves into the solutions and underlying principles of a typical "6.4 Practice Rectangles" worksheet, commonly found in sixth-grade mathematics curricula. We will dissect the problems, providing detailed step-by-step solutions and explanations, thereby serving as a valuable resource for students, parents, and educators alike. The focus will be on understanding the concepts of area and perimeter of rectangles, crucial components of elementary geometry. The "6.4 practice rectangles answer key with work" is not simply a collection of answers; it's a tool for reinforcing geometric understanding.
Understanding Rectangles: Area and Perimeter
Before diving into specific problem sets within the "6.4 practice rectangles answer key with work," it's crucial to establish a foundational understanding of rectangles, their properties, and how to calculate their area and perimeter.
A rectangle is a quadrilateral (a four-sided polygon) with four right angles. Opposite sides of a rectangle are parallel and equal in length. We typically denote the length of a rectangle as 'l' and the width as 'w'.
Area: The area of a rectangle is the amount of space enclosed within its boundaries. It is calculated by multiplying the length and the width: Area = l × w. The unit of area is always squared (e.g., square centimeters, square inches).
Perimeter: The perimeter of a rectangle is the total distance around its edges. It is calculated by adding up the lengths of all four sides: Perimeter = 2l + 2w or Perimeter = 2(l + w). The unit of perimeter is always a linear unit (e.g., centimeters, inches).
Detailed Analysis of "6.4 Practice Rectangles" Problems
Let's assume a typical "6.4 practice rectangles" worksheet includes problems of varying difficulty, encompassing different aspects of area and perimeter calculations. The following examples demonstrate the problem-solving approach and the rationale behind each step. The specific problems and their corresponding numbers will vary depending on the specific worksheet, but the principles remain the same. This is the essence of a good "6.4 practice rectangles answer key with work."
Example Problem 1: Finding the Area
Problem: A rectangle has a length of 8 cm and a width of 5 cm. Find its area.
Solution: Area = l × w = 8 cm × 5 cm = 40 cm².
Work: The solution clearly shows the formula used (Area = l × w) and the substitution of values, leading to the correct answer with the appropriate unit (cm²). This demonstrates the type of detailed working expected in a comprehensive "6.4 practice rectangles answer key with work."
Example Problem 2: Finding the Perimeter
Problem: A rectangle has a length of 12 inches and a width of 7 inches. Find its perimeter.
Solution: Perimeter = 2(l + w) = 2(12 inches + 7 inches) = 2(19 inches) = 38 inches.
Work: Similar to the previous example, the formula is clearly stated, and the calculations are shown step-by-step, resulting in the correct answer with the appropriate unit (inches). This level of detail is crucial for a helpful "6.4 practice rectangles answer key with work."
Example Problem 3: Word Problem Involving Area and Perimeter
Problem: A rectangular garden has an area of 72 square feet. If the length of the garden is 9 feet, what is its width and perimeter?
Solution:
Find the width: Area = l × w => 72 sq ft = 9 ft × w => w = 8 ft
Find the perimeter: Perimeter = 2(l + w) = 2(9 ft + 8 ft) = 34 ft
Work: This example demonstrates a multi-step problem requiring the application of both area and perimeter formulas. The step-by-step solution, clearly showing the derivation of the width and then the calculation of the perimeter, is essential for a clear "6.4 practice rectangles answer key with work."
Example Problem 4: Problems involving unknown sides
These problems require students to use their understanding of the properties of rectangles (opposite sides are equal) to solve for missing side lengths before calculating area or perimeter. These types of problems enhance comprehension and the usage of the "6.4 practice rectangles answer key with work" as a tool for understanding rather than just answers.
Advanced Problems (for higher-level worksheets):
More advanced problems might include:
Problems involving unit conversions (e.g., converting inches to feet before calculating area).
Problems involving fractions or decimals for side lengths.
Problems requiring students to solve for unknown side lengths given the area or perimeter.

For a less-expensive grayscale paperback version, see ISBN 9781680923254. Prealgebra 2e is designed to meet scope and sequence requirements for a one-semester prealgebra course. The text introduces the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics. Students who are taking basic mathematics and prealgebra classes in college present a unique set of challenges. Many students in these classes have been unsuccessful in their prior math classes. They may think they know some math, but their core knowledge is full of holes. Furthermore, these students need to learn much more than the course content. They need to learn study skills, time management, and how to deal with math anxiety. Some students lack basic reading and arithmetic skills. The organization of Prealgebra makes it easy to adapt the book to suit a variety of course syllabi. |
