A scale factor of 2.
The scale factor is 1 to 150
A scale factor of 2 means everything is shown in half the size of the original.
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
For areas: Square the Scale Factor.
If a big triangle has a base length of 6, and a small triangle has a corresponding base length of 3, the scale factor from large to small is 2/1 (or 2). The scale factor from small to large would be 1/2.

The area is directly proportional to the square of the scale factor. If the scale factor is 2, the area is 4-fold If the scale factor is 3, the area is 9-fold If the scale factor is 1000, the area is 1,000,000-fold
The dilation of 22 with scale factor 2.5 is 55.The formula for finding a dilation with a scale factor is x' = kx (k = scale factor), so x' = 2.5(22) = 55.

if two polygons are similar, then the ratio of the length of 2 corresponding sides is called a scale factor
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
