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
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.
To find the scale factor, we can divide the dimensions of the enlarged artwork by the dimensions of the original artwork.
The width scale factor is found by dividing the width of the enlarged artwork (3.15") by the width of the original artwork (2.25"):
3.15 / 2.25 = 1.4
The height scale factor is found by dividing the height of the enlarged artwork (2.8") by the height of the original artwork (2"):
2.8 / 2 = 1.4
Therefore, the scale factor used to create the copy of the original artwork is 1.4.
To find the scale factor, we can divide the corresponding dimensions of the copy by the dimensions of the original artwork.
For the width, we divide 3.15" by 2.25":
Scale factor (width) = 3.15" / 2.25" = 1.4
For the height, we divide 2.8" by 2":
Scale factor (height) = 2.8" / 2" = 1.4
The scale factor for both dimensions is the same, which is 1.4. Therefore, Bobby used a scale factor of 1.4 to create the copy of the original artwork.
