The required scale factor for the small rectangle is 8.

Given that,
Rectangle a is a 2 by 4 would a be 4 by 8,
To determine the scale factor,

What is the scale factor?

The scale factor is defined as the ratio of modified change in dimensions to original dimensions


Area of the rectangle = product of dimensions = length * width
Area of the former rectangle = 2 * 4

                                                = 8
Area of the later rectangle = 4 * 8 = 32
                                           
Scale factor = area of the later rectangle/area of the former rectangle
                    = 32 / 8
                    = 8


Thus, the required scale factor for the small rectangle is 8.
