What is a scale drawing?

Back

A scale drawing is a representation of an object or place that is proportionally smaller or larger than the actual size, using a specific ratio to maintain the correct dimensions.

Front

What does the term 'scale' mean in the context of drawings?

Back

In drawings, 'scale' refers to the ratio of the size of the drawing to the size of the actual object. For example, a scale of 1 cm = 0.5 m means that 1 cm on the drawing represents 0.5 m in reality.

How do you solve a proportion?

Back

To solve a proportion, you can cross-multiply the two ratios and then solve for the unknown variable.

Front

If a scale model is 10 cm tall and the scale is 1 cm = 2 m, how tall is the actual object?

Back

The actual object is 20 m tall.

Front

What is the formula to find the actual distance using a map scale?

Back

Actual Distance = Map Distance × Scale Factor.

Front

If the scale of a map is 1 in:50 mi, what does this mean?

Back

This means that 1 inch on the map represents 50 miles in reality.

Front

What is the relationship between similar figures?

Back

Similar figures have the same shape but may differ in size. Their corresponding sides are in proportion.

Front

How do you find the width of a larger rug if two rugs are similar?

Back

Set up a proportion using the corresponding dimensions of the two rugs and solve for the unknown width.

Back

Cross-multiply to get 21 * 8 = 6 * x.

Front

If a model is 5 cm tall and represents a building that is 10 m tall, what is the scale?
