Question

Choose the correct option regarding $\text{Scale Factor}$.

• A. It is the scale size to which the dimensions of original shape are added to get a resulting shape.
• B. It is the scale size by which the original shape is divided to get a resulting shape.
• C. It is the scale size by which the original shape is multiplied to get a resulting shape.

Answer 1

The correct option is C It is the scale size by which the original shape is multiplied to get a resulting shape.

By definition of scale factor we know that it is the scale size by which the original shape is multiplied to get a resulting shape.

For example,

Length of a line is 10 inches.

If length of the line increased by a scaling factor of 2, then its resulting length will be $(10\times \text{scale factor})\text{inches.}$

$\Rightarrow 10\times 2=20\text{inches.}$
