Dilation could result in an enlargement or a reduction. When the scale factor is less than 1, the result is a reduction. The coordinates of the trapezoid are
A(- 5, - 2)
B(- 1, - 2)
C(- 2, 1)
D(- 4, 1)
If the trapezoid is dilated by a scale factor of 1/2,
the center would be (3, 4) * 1/2 = (1.5, 2)
A' = (- 5, - 2) * 1/2 = (- 2.5, - 1)
B' = (- 1, - 2) * 1/2 = (- 0.5, - 1)
C' = (- 2, 1) * 1/2 = (- 1, 0.5)
D' = (- 4, 1) * 1/2 = (- 2, 0.5)
