The area scale factor is the square of the side length scale factor.
The areas will be proportional to (scale)2
Perimeter will scale by the same factor. Area of the new figure, however is the original figures area multiplied by the scale factor squared. .
For areas: Square the 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
For a, it tells you how many times the side lengths grew or shrunk.For b, it tells you that the perimeter grows or shrinks: scale factor times original perimeter.For c, it tells you that the area grows or shrinks: scale factor squared times the original area.
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
The areas are related by the square of the scale factor.
100 is the scale factor
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
