Use the image to answer the question.
An illustration shows two rectangles. The first is horizontally positioned lengthwise and the second is positioned slanting lengthwise to the left. The first rectangle has a base length of 5 inches and vertical width of 3 inches. The tilted second rectangle has a length of 9 inches and a width of 5.4 inches.
What scale factor was used to enlarge the rectangle in the image? The measurements refer to inches. Give your answer as a decimal.
(1 point)
To find the scale factor used to enlarge the rectangle in the image, we can compare the vertical widths of the two rectangles.
The vertical width of the first rectangle is 3 inches. The vertical width of the second rectangle is 5.4 inches.
To find the scale factor, we divide the vertical width of the second rectangle by the vertical width of the first rectangle:
Scale factor = 5.4 inches / 3 inches = 1.8
Therefore, the scale factor used to enlarge the rectangle in the image is 1.8.
