What scale factor was used to enlarge the rectangle in the image the measurements referred to inches give your answer as a decimal 3 in 5 in 9 in 5.4 in
To find the scale factor, we can divide the corresponding lengths of the original and enlarged rectangles.
The original rectangle has a length of 3 inches and an enlarged length of 5 inches. Therefore, the scale factor for the length is 5/3 = 1.67.
The original rectangle has a width of 9 inches and an enlarged width of 5.4 inches. Therefore, the scale factor for the width is 5.4/9 ≈ 0.6.
Since we are asked to find the scale factor used to enlarge the rectangle, we will take the average of these two scale factors: (1.67 + 0.6) / 2 = 1.135.
Therefore, the scale factor used to enlarge the rectangle is approximately 1.135.
