Question

The area of Square A is 36 square cm. The area of Square A’(A Prime) is 225 ᶜᵐ². What possible transformations did the square undergo? 

Answer 1

A possible transformation is a scale. Since the area changed by

$\frac{225}{36}=\frac{25}{4}$

then a possible transformation was a scale by 25/4. A scale by a ratio bigger than one is a dilation.

Then the answer is B.
