Question

Sara draws a square of side length $2$ inch and she rescaled it by a scale factor such that side length of new square becomes $3$ inch.


What is the scale factor?

• A. $\frac{2}{3}$
• B. $\frac{3}{2}$
• C. $\frac{1}{2}$
• D. $\frac{1}{3}$

Answer 1

The correct option is B $\frac{3}{2}$


As we know,
Side length of new square = Side length of original square $\times$ Scale factor

$⟹3=2\times$ Scale Factor

$\therefore \text{Scale Factor}=\frac{3}{2}$

Therefore, (b) is the correct option.
