The floor plan of a ballroom is shown at right. The scale is 3 centimeters : 4 meters. What are the length and width of the ballroom? Find the ballroom’s area.
Length:
Width:
Area:<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n To accurately answer this question, I would need to see the floor plan of the ballroom<\/strong>, as it contains the actual measurements in centimeters. Since no image is currently shown or attached, I will explain how to solve this type of problem step-by-step<\/strong> using a hypothetical example, and how to apply the scale conversion<\/strong> and area formula<\/strong>.<\/p>\n\n\n\n The scale provided is:<\/p>\n\n\n\n Let\u2019s say, for example:<\/p>\n\n\n\n Use a proportion:<\/p>\n\n\n\n $\\frac{3 \\text{ cm (drawing)}}{4 \\text{ m (actual)}} = \\frac{12 \\text{ cm}}{x \\text{ m}}$<\/p>\n<\/blockquote>\n\n\n\n Solve for $x$:<\/p>\n\n\n\n $$ Repeat for width:<\/p>\n\n\n\n $$ So:<\/p>\n\n\n\n Use the formula for the area of a rectangle:<\/p>\n\n\n\n $$ This problem involves scale drawing and unit conversion<\/strong>, which is a common application in geometry and real-world measurements such as architecture or engineering. The scale provided\u20143 centimeters : 4 meters<\/strong>\u2014is crucial. It allows us to translate the measurements from the drawing (in centimeters) to actual real-world dimensions (in meters). This ratio tells us that every 3 centimeters on the floor plan represents 4 meters in reality.<\/p>\n\n\n\n To find the real dimensions, we use proportional reasoning. This involves setting up a ratio using the known scale and the measured value from the plan and solving for the unknown actual value. For example, if the drawing shows 12 centimeters as the length, we set up the proportion $\\frac{3}{4} = \\frac{12}{x}$, where $x$ is the real-life measurement. Cross-multiplying and solving gives us the real-world value.<\/p>\n\n\n\n Once both the length<\/strong> and width<\/strong> are found, we apply the formula for the area of a rectangle:<\/p>\n\n\n\n $$ This gives us the total space inside the ballroom, which is useful for event planning, capacity estimation, or flooring costs.<\/p>\n\n\n\n If you can upload or describe the actual dimensions shown in centimeters<\/strong> on the drawing, I can give the exact answer<\/strong>.

1. Understand the Scale:<\/strong><\/h4>\n\n\n\n
\n
This means for every 3 cm on the drawing<\/strong>, the actual ballroom measures 4 meters<\/strong> in real life.<\/li>\n<\/ul>\n\n\n\n2. Measure the Dimensions on the Drawing:<\/strong><\/h4>\n\n\n\n
\n
3. Convert Drawing Measurements to Actual Measurements:<\/strong><\/h4>\n\n\n\n
\n
x = \\frac{12 \\times 4}{3} = \\frac{48}{3} = 16 \\text{ meters}
$$<\/p>\n\n\n\n
x = \\frac{9 \\times 4}{3} = \\frac{36}{3} = 12 \\text{ meters}

4. Find the Area:<\/strong><\/h4>\n\n\n\n
\\text{Area} = \\text{Length} \\times \\text{Width}
