Question

A. Rectangles 2 and 4

Answer 1

Answer: C. Rectangles 1 and 3

Step-by-step explanation:

1. By definition, two rectangles are similar if they have equal shape bot do not have equal sizes.

2. You can know it the rectangle 1 and 3 are similar by the following proportions:

$\frac{l_1}{l_3}=\frac{w_1}{w_3}$

Where $l_1$ is the lenght of the rectangle 1, $l_2$ is the lenght of the rectangle 2, $w_1$ is the width of the rectangle 1 and $w_2$ is the width of the rectangle 2.

3. Subtitute values:

$\frac{11m}{14m}=\frac{2.2m}{2.8m}$

$0.78=0.78$

4. Then, the rectangle 1 and 3 are similar.
