Bobby draws an artwork measuring 2.25“ x 2“. He makes a copy of the artwork enlarging it so that its dimensions are now 3.15“ x 2.8“. 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 corresponding dimensions of the enlarged artwork by the dimensions of the original artwork.

For the width:
Scale factor = (3.15") / (2.25") ≈ 1.4

For the height:
Scale factor = (2.8") / (2") = 1.4

Hence, the scale factor used to create the copy of the original artwork is approximately 1.4.
