Jobs that use scale factor include architects, who use it to create scaled drawings of buildings and structures; engineers, who use it to design and model various systems and components; and urban planners, who use it to create scaled maps and plans for cities and communities. Scale factor is a crucial concept in these professions as it allows for accurate representation and analysis of objects and spaces at different sizes.
A scale factor requires two measures.
The number used to multiply the lengths of a figure to stretch or shrink it to a similar image. If we use a scale factor of 3, all the corresponding lengths in the original side lengths will be multiplied by three.
You find the scale factor on a triangle by dividing the short side by the long side.
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
Every part of the original scales by the same scale factor. By using a segment of the original you will determine the scale factor by dividing the length of the image by the length of the original.
The way you use a scale factor to enlarge a triangle is to multiply each side of the triangle by that scale factor. Your triangle will then be that many times larger.
a scale factor of 4.5 is your answer
New perimeter = old perimeter*scale factor New area = Old area*scale factor2

You increase the scale factor.
Tautologically!
The area scale factor is the square of the side length scale factor.
No, there cannot be a zero in any scale factor.
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.
1 shape cannot have a scale factor. A scale factor is something (a factor) that relates one shape to another.
