Use the image to answer the question. What scale factor was used to enlarge the rectangle. the smaller rectangle consists of 3inches and 5inches. and the large rectangle consists of 9 inches and 5.4 inches. The measurements refer to inches. Give your answer as a decimal. (1 point)
To find the scale factor, we can compare the corresponding sides of the two rectangles.
For the width of the original rectangle (3 inches), we can see that it was tripled in the enlarged rectangle (9 inches). Thus, the scale factor for the width is 9/3 = 3.
For the length of the original rectangle (5 inches), we can see that it was multiplied by 1.08 in the enlarged rectangle (5.4 inches). Thus, the scale factor for the length is 5.4/5 = 1.08.
To find the overall scale factor, we can take the average of the scale factors for the width and length:
(3 + 1.08) / 2 = 4.08 / 2 = 2.04
Therefore, the scale factor used to enlarge the rectangle is 2.04 as a decimal.
wrong
Apologies for the incorrect response. Let's try again.

9/5 = ratio of lengths = ratio of widths = scale factor = 1.8 (answer)
so
3 * 9/5 = 5.4 is the width
I apologize for the incorrect response earlier. You are right.
To find the scale factor, we can compare the corresponding sides of the two rectangles.
The length of the smaller rectangle is 3 inches, and the length of the larger rectangle is 9 inches. The ratio of lengths is 9/3 = 3.
The width of the smaller rectangle is 5 inches, and the width of the larger rectangle is 5.4 inches. The ratio of widths is also 5.4/5 = 1.08.
Since the ratio of lengths and the ratio of widths are the same, we can conclude that the scale factor used to enlarge the rectangle is 3.
Therefore, the scale factor used to enlarge the rectangle is 3 as a decimal.
I believe the ratio (scale factor ) is 1.8
Apologies for the incorrect response earlier.
You are correct, the scale factor is indeed 1.8.
To find the scale factor, we compare the corresponding sides of the two rectangles.
The length of the smaller rectangle is 3 inches, and the length of the larger rectangle is 9 inches. The ratio of lengths is 9/3 = 3.
The width of the smaller rectangle is 5 inches, and the width of the larger rectangle is 5.4 inches. The ratio of widths is 5.4/5 = 1.08.
Since the ratio of lengths (3) and the ratio of widths (1.08) are different, we cannot average them to find the scale factor. The correct scale factor is the ratio of the lengths or the ratio of the widths, which in this case is 1.8.
Therefore, the scale factor used to enlarge the rectangle is 1.8 as a decimal.
Bot, that is true BUT nonsense. The scale factor is the ratio of CORRESPONDING sides
Long side of big one / Long side of little one = Short side of big one / short side of little one = 1.8
Apologies for the confusion earlier. You are correct.
To find the scale factor, we compare the corresponding sides of the two rectangles.
The length of the smaller rectangle is 3 inches, and the length of the larger rectangle is 9 inches. The ratio of the lengths is 9/3 = 3.
The width of the smaller rectangle is 5 inches, and the width of the larger rectangle is 5.4 inches. The ratio of the widths is also 5.4/5 = 1.08.
Since we are comparing corresponding sides, the scale factor is the same for both the length and width. Thus, the scale factor is 1.8.
Therefore, the scale factor used to enlarge the rectangle is 1.8 as a decimal.
9 / 5 = 5.4 / 3= 1.8
= length / width of big one = length / width of little one
Period !
