You can set up a proportion and solve for the unknown side. Say that your rectangle has a short side that measures 4. The long side, unknown at this time, is x. The scale factor of the long side to the short side is 2/1 or 2:1. That would mean that the ratio of the actual side measurements, long side to short side, would be x/4. Set up a proportion where that ratio and the scale factor are equal to each other. Cross multiply and solve for x.
x/4 = 2/1
x = 8
The long side of the rectangle would measure 8.

If you know one of the sides of both the rectangles than you just divide them by one another to find the scale factor.
Finding the scale factor for two polygons is simple to do. All you have to do is find the angles in a rectangle.
you make it into a fraction and multipy it by any giant one. then you have to REDUCE it
well.... first off you have to find the scale factor...

You find the scale factor on a triangle by dividing the short side by the long side.

To find the new area, you have to multiply the original area by the square of the scale change. For example, you have a rectangle with adjacent sides of 3 and 4. Another rectangle has the same dimensions but with triple the scale. The original rectangle's area is 12. Multiply that by 9, which is the square of the new scale, and you get an area of 108. That matches up with the area of the new rectangle, which has adjacent sides of 12 and 9.
A scale Factor is Algbrea so you have to... x - + and/or divided.
how do you find the scale factor of two circles
The linear scale factor is 100.
how to do a scale factor of cylinder is that you find the base and the height and the length of A area hope you like my examples.
The two scale factors are reciprocals of one another.
