Rectangles A and B are not similar, because 3/2.5 is 1.2, while 5/4.5 is about 1.1. This means that the two rectangles cannot be increased or decreased by any scale factors to equal each other. Rectangles A and C are not similar, because 3/10 is 0.3, while 5/18 is about 2.8. Rectangles B and C, however, are similar, because 2.5/10 is 0.25, and 4.5/18 is 0.25 as well. This means that Rectangle B can be increased using a scale factor of 4 to make it equal to Rectangle C.

Yes. All squares are similar because, by definition, all the sides of a square are the same. This means that there is only one value to consider when finding out whether or not another square is similar to it. All numbers are divisible by another number, even if the quotient is a decimal, meaning that all squares are similar.

Answer:
120 cm
Step-by-step explanation:
If you rearrange the lines you will get a rectangle whose sides are 25 cm and 35 cm.
To get a triangle, move the lines inside the rectangle keeping them parallel to the lines in front of them.
Let P the perimeter of the rectangle:
P = 25*2 + 35*2 = 50+70 = 120 cm
