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:
[tex]\frac{l_1}{l_3}=\frac{w_1}{w_3}[/tex]
Where [tex]l_1[/tex] is the lenght of the rectangle 1, [tex]l_2[/tex] is the lenght of the rectangle 2, [tex]w_1[/tex] is the width of the rectangle 1 and [tex]w_2[/tex] is the width of the rectangle 2.
3. Subtitute values:
[tex]\frac{11m}{14m}=\frac{2.2m}{2.8m}[/tex]
[tex]0.78=0.78[/tex]
4. Then, the rectangle 1 and 3 are similar.
