A rectangle has a length that is twice its width. If the perimeter is 36 meters, what is the area of the rectangle?
["Rectangle Perimeter & Area: Solving for Area When Length is Twice the Width", "If you're studying geometry or tackling a math problem, understanding how rectangle dimensions relate to perimeter and area can simplify complex questions. One common scenario involves rectangles where the length is twice the width and the perimeter is known. This article breaks down how to find the rectangle’s area when these conditions are met.", "### Understanding the Rectangle Dimensions", "Let’s begin with the key information:\n- The length (L) of the rectangle is twice its width (W), or mathematically:\n [\n L = 2W\n ]\n- The perimeter (P) is given as 36 meters.", "For any rectangle, the perimeter is calculated using the formula:\n[\nP = 2(L + W)\n]\nSubstituting the expression for ( L ) into the perimeter formula gives:\n[\n36 = 2(2W + W) = 2(3W) = 6W\n]", "### Solving for Width and Length", "Now solve for ( W ):\n[\n6W = 36 \Rightarrow W = \frac{36}{6} = 6 \ ext{ meters}\n]\nWith the width known, find the length:\n[\nL = 2W = 2 \ imes 6 = 12 \ ext{ meters}\n]", "### Calculating the Area", "The area (A) of a rectangle is the product of its length and width:\n[\nA = L \ imes W = 12 \ imes 6 = 72 \ ext{ square meters}\n]", "### Final Answer", "This rectangle has dimensions 12 meters by 6 meters, and its area is 72 square meters. This is a classic example of how algebraic relationships within geometric formulas enable quick solutions when variables are defined in terms of each other.", "Understanding these principles helps not only in exams but also in real-world applications—from designing rooms and rooms to landscaping and architecture, where knowing perimeter and area is essential.", "Key Takeaway: When length is twice the width and perimeter is 36 meters, the rectangle’s area is 72 m².
