Bobby draws an artwork measuring 2.25 inches by 2 inches. He makes a copy of the artwork, 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 are 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 inches by 2 inches.
The dimensions of the copy are 3.15 inches by 2.8 inches.
So, the scale factor is (3.15 inches / 2.25 inches) = 1.4
Or, (2.8 inches / 2 inches) = 1.4
The scale factor is 1.4 (rounded to one decimal place).
