Parallelogram JKLM was rotated 270° clockwise and then dilated by a scale factor of 1/8.

From the distance formula

JK = 16

KL = [tex]2\sqrt{165}[/tex]

LM = 16

MJ = [tex]2\sqrt{165}[/tex]

Similarly,

J"K" = 2

K"L" = [tex]\sqrt{10}[/tex]

L"M"=2

M"J"= [tex]\sqrt{10}[/tex]

If a parallelogram is reflected about the y-axis then the Y-coordinate of each edge will be unchanged while the X-coordinate will become -X.

so coordinates of parallelogram JKLM after reflection about y-axis will be

J≡(8,16)

K≡(-8,16)

L≡(-16,-8)

M≡(0,-8)

JK = 16

KL = [tex]2\sqrt{165}[/tex]

LM=16

MJ = [tex]2\sqrt{165}[/tex]

J"K"/JK = 2/16 = 1/8

it means JKLM was dilated by a factor of 1/8

Hence, Parallelogram JKLM was reflected about the y-axis and then dilated by a scale factor of 1/8.
