To find the scale factor, we can divide the corresponding side lengths of the enlarged artwork by the corresponding side lengths of the original artwork.
For the length: scale factor = 3.15 inches / 2.25 inches = 1.4
For the width: scale factor = 2.8 inches / 2 inches = 1.4
Therefore, the scale factor that Bobby used to create the copy of the original artwork is 1.4.
