Question

enlarging it so that its dimensions are now 3.15 inches by 2.8 inches. What scale factor did he use to
create the copy of the original artwork? Write your answer as a decimal

Answer 1

To find the scale factor, we can divide the dimensions of the enlarged artwork by the original artwork.

For the length: 3.15 inches / 2.25 inches = 1.4
For the width: 2.8 inches / 2 inches = 1.4

Since both dimensions have the same scale factor, Bobby used a scale factor of 1.4 to create the copy of the original artwork.
