Bobby draws and artwork measuring 2.25“ x 2“ He makes a copy of the artwork enlarging it so that it does dimensions are now 3.15” x 2.8” what scale factor does he use to create the copy of the original artwork write your answer as a decimal
To find the scale factor, we need to divide the dimensions of the copy by the dimensions of the original artwork.
The dimensions of the original artwork are 2.25" x 2".
The dimensions of the copy are 3.15" x 2.8".
To find the scale factor for the width, we divide the width of the copy by the width of the original artwork: 3.15"/2.25" = 1.4.
To find the scale factor for the height, we divide the height of the copy by the height of the original artwork: 2.8"/2" = 1.4.
The scale factor is the same for both the width and the height, and it is equal to 1.4.
Therefore, the scale factor used by Bobby to create the copy of the original artwork is 1.4 (written as a decimal).
