Question

2. Use the scale factor of 1:3 to create a newfigure.5 in3.5 in

Answer 1

The scale factor 1 : 3 means:

`\frac{\text{ side length of the original figure}}{side\text{ length of the new figure}}=(1)/(3)`

Cross multiplying, we get:

`\text{side length of the original figure}\cdot3=\text{side length of the new figure}`

If the original figure has the measures 5 in and 3.5 in, then new lengths are:

3x5 = 15 in

3x3.5 = 10.5 in
