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.
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
The areas are related by the square of the scale factor.
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
For areas: Square the Scale Factor.
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.
