Answer:
Not similar
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.
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.
Because these values are not equal, the rectangles are not similar.
