7. The perimeter after dilation is 48 units.
Option: c.
9. The dilation scale factor for the fence - scale factor of 2.5.
Option: a.
<u>Explanation:</u>
Any object with perimeter will change by the same amount of dilation scale factor.
i.e. the scale factor is 6, then the perimeter of the object is multiplied by 6.
7) the figure has perimeter 12 initially and it is dilated with the factor of 4.
So the perimeter after dilation = 4×12.
= 48.
∴The perimeter of the figure after dilation is 48 units.
9) Given that Shawn wants to make the perimeter of his fence 2.5 times.
Then for the dilation the dimensions for the fence needs Scale factor of 2.5.
