Answer:
Not similar
Step-by-step explanation:
For a rectangle you would make a equation with length a over length b equalibg width a over width b. I'll use the problem and show it in an equation below.
[tex] \frac{12}{24} = \frac{8}{18} [/tex]
There are a few ways to solve this, 1, by simplifying, and the other cross multiplying. I like cross multiplying more, so I'll explain it like that. To cross multiply you multiply the numerator of one fraction by the denominator of the other.
[tex]12 \times 18 = 216 \\ 24 \times 8 = 192[/tex]
Because these values are not equal, the rectangles are not similar.
