Often when working a problem with a scale factor, you are given two similar shapes, and a missing side. For example, you could be given a rectangle with sides A: 3 units and side B: 9 units. Then, you are given another similar rectangle, with side A: 6 units and side B: unknown. To solve this problem, you can simply create a proportion, known in this case as a scale factor.
Similar to using a map to predict travel times on a road trip, you can simply create a proportion, in this case, 6:3, which simplifies to 2:1. In this case, the scale factor is 2, so the length of a similar side in the 1st shape is multiplied by 2 to get the length of the same side in the other (2nd) shape. Knowing this side is 9 in the first, and the scale factor is two, we know that the similar side in the 2nd shape is going to be 9 x 2 = 18 units long.

What happens to the perimeter when a rectangle is enlarged by a scale factor of 5?
if the length and breadth are increased by 5 times each area becomes 25 times
How do you dilate a scale factor?
You increase the scale factor.
What are the relationship between the area scale factor and the side length scale factor of similar figures?
The area scale factor is the square of the side length scale factor.
What is the name of the common ratio of corresponding sides of similar figures?
The scale factor.The scale factor.The scale factor.The scale factor.
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
Perimeter ratio 100 and find scale factor?
The linear scale factor is 100.
How does scale factor relate to perimeter?
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.
What does the scale factor between two similar figures tell you about the perimeter?
The perimeter will scale by the same factor.
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
What is the relationship between scale factor and perimeter?
It is a strict linear relationship. Double the size, double the perimeter. The area, however, increases by the square of the scale factor.
How does the perimeter change when the dimensions are changed by a scale factor of 3?
The perimeter, being a linear measure, also changes by a factor of 3.
What is the algebraic equation if 12 is the perimeter the scale factor is r and the new perimeter is p?
12r = p
If two polygons are similar how can you find the scale factor from one polygon to the other?
divide the perimeter by 27 the multiply it by 3 and then u get the answer
How is the perimeter and the size change factor related?
If you change the scale factor of a geometric figure by a factor "x", that is, keeping the new figure similar to the old one, the perimeter (which is also a linear measurement) will change by the SAME factor "x".Note that any area will change by a factor of x squared.
What is the perimeter of Minnesota in feet?
I highly doubt anyone knows. Perhaps, find a large map of Minnesota, estimate its perimeter (maybe by surrounding the border with string) then multiply by the proper scale factor.
What is the perimeter of a rectangle 7 in by 2 in enlarged by the scale factor of 1.5?
A rectangle 10.5 x 3 will have a perimeter of 27 in.
