Similar Rectangles: Two rectangles are similar when the corresponding adjacent sides have the same ratio
Taking the ratios of the Length to breadth
rectangle 1: rectangle 2
[tex]\begin{gathered} \frac{CD}{AD}\text{ :}\frac{GH}{EH} \\ \frac{5\operatorname{cm}}{4\operatorname{cm}}\text{ : }\frac{3\operatorname{cm}}{2\operatorname{cm}} \end{gathered}[/tex][tex]\begin{gathered} \frac{5}{4}\text{ : }\frac{3}{2} \\ 1.25\text{ : 1.5} \end{gathered}[/tex]The ratio of the sides is 1.25 : 1.5
Since the values are different, the rectangles are not similar
