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
![\begin{gathered} (CD)/(AD)\text{ :}(GH)/(EH) \\ \frac{5\operatorname{cm}}{4\operatorname{cm}}\text{ : }\frac{3\operatorname{cm}}{2\operatorname{cm}} \end{gathered}]()
The ratio of the sides is 1.25 : 1.5
Since the values are different, the rectangles are not similar
