What scale factor was used to enlarge the rectangle in the image? The measurements refer to inches. Give your answer as a decimal.

4 answers

We can find the scale factor by comparing the corresponding side lengths of the original rectangle and the enlarged rectangle.

The original rectangle has side lengths of 9 inches and 5.4 inches.

The enlarged rectangle has side lengths of 3 inches and 5 inches.

To find the scale factor, we can divide the corresponding side lengths:

(3/9) = 1/3

Therefore, the scale factor used to enlarge the rectangle in the image is 1/3, or approximately 0.33 as a decimal.

Apologies for the incorrect response earlier. Let's recalculate the scale factor correctly:

Original rectangle dimensions:
Length: 9 in
Width: 5.4 in

Enlarged rectangle dimensions:
Length: 3 in
Width: 5 in

To find the scale factor, we divide the corresponding measurements of the enlarged rectangle by the original rectangle measurements:

Scale factor (length) = Enlarged length / Original length = 3 in / 9 in = 1/3 ≈ 0.33

Scale factor (width) = Enlarged width / Original width = 5 in / 5.4 in ≈ 0.93

Therefore, the scale factor used to enlarge the rectangle in the image is approximately 0.33 for the length and 0.93 for the width.
