Final answer:
The scale 1 cm to 3 meters in a drawing means each centimeter on the drawing corresponds to 3 meters of the actual building. This maintains the proportions in a manageable size, allowing for accurate representation of large structures on paper.
Step-by-step explanation:
The scale of a drawing indicates the relationship between the measurements on the drawing and the actual measurements of the object being drawn. In this case, a scale of 1 cm to 3 meters means that for every centimeter measured on the drawing, the actual building is 3 meters in that dimension. This scale helps to produce a smaller representation of a larger object, making it easier to manage and visualize without losing the proportion of its dimensions.
Examples:
- Scale drawing problem: A meeting room in a scale drawing measures 1.5 cm by 2.5 cm with a scale of 1 cm to 2 meters. To find the actual area, first convert dimensions into actual meters, then calculate the area in square meters.
- Running distance conversion: 10 kilometers are equal to 10,000 meters, so Samir would have run 10,000 meters in the race.
