Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or area that maintains the proportions of the original, using a specific ratio to reduce or enlarge its size.

What does the scale 5 cm : 2 m mean?

Back

It means that every 5 centimeters on the drawing represents 2 meters in real life.

Front

How do you convert real-life measurements to scale measurements?

Back

To convert, use the scale ratio to find the equivalent measurement in the drawing. For example, if the scale is 1 cm : 4 ft, then 8 ft in real life would be 2 cm in the drawing.

If a parking lot is 34 meters wide in real life, how wide is it in a drawing with a scale of 5 cm : 2 m?

Back

85 cm.

How do you find the actual size from a scale drawing?

Back

Multiply the measurement on the drawing by the scale factor to find the real-life size.

Front

If a tent is 6 feet wide in real life and the scale is 1 inch : 3 feet, how wide is it in the drawing?
