Step-by-step explanation:
Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

Therefore, those rectangles are congruent.
it's D becuase when you round all of them 124.2 is the only one thats different.

125.3 Rounded is 125
124.9 Rounded is 125
124.2 Rounded is 124
