Answer:

The scale factor can either increase or decrease the size of an object. To find the scale factor of dilation:

[tex]\textsf{Scale factor} = \dfrac{\textsf{Dimension of the new shape}}{\textsf{Dimension of the original shape}}[/tex]

For these questions:

  • new shape = Figure A
  • original shape = Figure B

Question 1

  • Top edge of Figure A = 9 units
  • Top edge of Figure B = 3 units

[tex]\sf \implies scale \ factor=\dfrac{9}{3}=3[/tex]

Question 2

  • Width of Figure A = 4 units
  • Width of Figure B = 6 units

[tex]\sf \implies scale \ factor=\dfrac46=\dfrac23[/tex]
