New perimeter = old perimeter*scale factor New area = Old area*scale factor2
For areas: Square the Scale Factor.
Square it.
Perimeter will scale by the same factor. Area of the new figure, however is the original figures area multiplied by the scale factor squared. .
The area changes by the square of the same factor.
The area scale factor is the square of the side length scale factor.
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
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
New perimeter = old perimeter*scale factor New area = Old area*scale factor2

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.
As you would find the surface area of a normal shape using scale factors: to find the volume scale factor cubed, therefore to find the surface area of the hypercube, you do the scale factor to the power of four. geoffrz450@yahoo.co.uk
The scale factor is usually stated as a linear enlargement factor. Therefore, the area enlargement factor is the square of the scale factor, in this instance, 9. The area of the original drawing was thus 396/9 = 44 cm2.
