The scale factor is 1 to 150
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.

You need information about a pre-image AND and image to work out a scale factor.
times by two
A scale factor is a number which scales, or multiplies, some quantity. A scale factor of two would mean to multiply whatever it is by two.
Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.
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
