Question

a drawing with a scale of 2:1 will be

select one:
a. twice the size of the object it represents
b. half the size of the object it represents

Explanation:

Understand scale notation

Using the Scale Interpretation knowledge point
A scale ratio is written in the standard format:

$$ \text{Drawing Size} : \text{Actual Size} $$

Analyze the given ratio

Using the Scale Interpretation knowledge point
For a scale of \(2:1\):

• The first number (2) represents the size on the drawing.
• The second number (1) represents the actual size of the object.

Determine the relative size

Using the Scale Interpretation knowledge point
Since \(2 > 1\), the drawing is larger than the actual object. Specifically, every 2 units on the drawing represent 1 unit on the actual object, meaning the drawing is twice the size of the object it represents.

Answer:

• a. twice the size of the object it represents (Correct answer)
• b. half the size of the object it represents
