To find the corresponding side length in the old figure, we can set up a proportion.
Let x be the corresponding side length in the old figure.
According to the given information, the scale factor is 3(new figure) to 2(old figure).
This can be written as:
3/2 = 9.9/x
To solve for x, we can cross multiply:
3x = 2 * 9.9
3x = 19.8
Divide both sides by 3:
x = 19.8 / 3
x = 6.6
Therefore, the corresponding side length in the old figure is 6.6.
The correct answer is B) 6.6.
The scale factor for two figures is 3(new figure) to 2(old figure). The new figure has a side of 9.9. What is corresponding side in the old figure?
