A rectangle has a length of 10 units and a width that is 3 units less than the length. What is the perimeter of the rectangle?
["Understanding the Perimeter of a Rectangle: A Practical Example", "When studying geometry, one of the fundamental concepts is the perimeter of a rectangle. If you’re curious about how to calculate the perimeter from given dimensions, a simple real-world example can clarify the process. In this case, consider a rectangle with a length of 10 units and a width that is 3 units less than the length. Let’s walk through the calculation step-by-step.", "### Step 1: Identify the Dimensions\nWe are told:\n- Length = 10 units\n- Width = Length – 3 units = 10 – 3 = 7 units", "### Step 2: Recall the Perimeter Formula\nThe perimeter ( P ) of a rectangle is calculated using the formula:\n[\nP = 2 \ imes (\ ext{Length} + \ ext{Width})\n]", "### Step 3: Plug in the Values\nSubstitute the known values into the formula:\n[\nP = 2 \ imes (10 + 7) = 2 \ imes 17 = 34\n]", "### Step 4: Final Answer\nTherefore, the perimeter of the rectangle is 34 units.", "### Why This Matters\nUnderstanding how to compute the perimeter using basic geometric formulas helps in various real-life applications, such as framing furniture, laying foundations, or designing rectangular spaces. It reinforces core algebraic and arithmetic skills essential for students and homeowners alike.", "Whether you're a teacher explaining key geometry concepts or someone tackling basic math problems, knowing how to derive perimeter from length and adjusted width is a valuable skill. So next time you encounter a rectangle with slightly reduced dimensions, recall the formula: subtract 3 from the length, add the length and width, and multiply by two.", "---", "🔍 SEO Keywords: perimeter of a rectangle, how to calculate rectangle perimeter, rectangle dimensions formula, length and width calculation, geometry problems, real-life geometry examples", "By integrating clear calculations and practical relevance, this article optimizes readability and search visibility for students and educators exploring foundational geometry."]
