Question

The scale on a drawing is 3:1. Which statement is true? Select two answers that apply.

Answer 1

The scale on a drawing is written so that the first number is the length on the drawing and the second number is the length in real life.

A scale of 3:1 means the drawing is 3 times the size of the actual object.

The two true answers would be:

A.  The scale drawing is three times the size of the actual object.

And

D.  If the actual object is 2 cm long, the scale drawing will be 6 cm long.

Answer 2

Answer:

A.

The scale drawing is three times the size of the actual object.

D.

If the actual object is 2 cm long, the scale drawing will be 6 cm long.

Step-by-step explanation:

The scale on a drawing is 3:1. This means that a feature in the drawing is 3 times the size of the feature in the actual object. For example:

If a feature on the actual object is 3 cm, the feature on the drawing will be 3*3 = 9 cm.

Similarly, If a feature on the actual object is 2 cm, the feature on the drawing will be 2*3 = 6 cm.

So among the given options, the following are correct:

A.

The scale drawing is three times the size of the actual object.

D.

If the actual object is 2 cm long, the scale drawing will be 6 cm long.
