• L= 16

  H= 12

• L= 2/3

  H= 3/5

When applying a scale factor of 2.5 to Figure B, what is the new length and height?

• L= 10

  H= 12

• L= 0.8

  H= 2.4

• L= 5

  H= 15

• L= 12

  H= 20

When applying a scale factor of 3 to Figure C, what is the new length and height?

• L= 3

  H= 3

• L= 2

  H=2

• L= 6

  W= 6

• L= 1.5
