What scale factor was used to enlarge the rectangle 3” x 5” in the image the measurements refer to inches give your answer as a decimal

Answer 1

To find the scale factor, we need to compare the original dimensions of the rectangle to the dimensions in the image.

The original dimensions are 3 inches by 5 inches. Let's assume the dimensions in the image are L inches by W inches.

To find the scale factor, we can divide the corresponding dimensions:

Scale factor = (L inches) / (3 inches) = (W inches) / (5 inches)

Since the scale factor is the same for both dimensions, we can set up the equation as:

L/3 = W/5

Cross-multiplying, we have:

5L = 3W

Dividing both sides by 5, we get:

L = (3/5)W

Therefore, the scale factor used to enlarge the rectangle in the image is 3/5 or 0.6.
