Question

PLEASE HELLP IM AWARDING 100 POINTS FOR THIS What is the scale factor, or constant of proportionality from Figure 1 to Figure 2?

Enter your answer as a decimal in the box.

Answer 1

4:9

Explanation:

Answer 2

Scale factor = 2.25

Explanation:

To find the scale factor between two similar shapes, we need to compare the corresponding sides of the shapes.

The scale factor is the ratio of the length of any side of one shape to the length of the corresponding side on the other shape.

From inspection of the given diagram, the ratio of the corresponding sides of the two similar figures is:

⇒ Figure 1 : Figure 2 = 8 : 18

Therefore, to find the scale factor from Figure 1 to Figure 2, divide the side length of Figure 2 by the corresponding side length of Figure 1:

`\implies \sf Scale\;factor=(18)/(8)=2.25`
