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 as a decimal

To find the scale factor, we need to divide the dimensions of the enlarged copy by the dimensions of the original artwork.

The scale factor for the width is 3.15 inches / 2.25 inches = 1.4.
The scale factor for the height is 2.8 inches / 2 inches = 1.4.
Therefore, the scale factor is 1.4.

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

Scale factor = (Enlarged artwork dimensions) / (Original artwork dimensions)

For the length:
Scale factor = 3.15 inches / 2.25 inches

For the width:
Scale factor = 2.8 inches / 2 inches

Calculating these values:

Scale factor (length) = 3.15 / 2.25 ≈ 1.4
Scale factor (width) = 2.8 / 2 ≈ 1.4

Since the length and width scale factors are equal, we can conclude that Bobby used a scale factor of approximately 1.4 to create the copy of the original artwork.

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

For the width, the scale factor is 3.15 inches (width of the copy) divided by 2.25 inches (width of the original):
Scale factor = 3.15 inches / 2.25 inches = 1.4

For the height, the scale factor is 2.8 inches (height of the copy) divided by 2 inches (height of the original):
Scale factor = 2.8 inches / 2 inches = 1.4

Since the scale factor for both the width and height is the same, we can conclude that Bobby used a scale factor of 1.4 to create the copy of the original artwork.
