The coordinates of point U' are (0, 28)
Explanations:The coordinates of triangle QUAD are:
Q(0, 0)
U(0, 4)
A(7, 4)
D(7, 0)
Center of dilation = (0, 0)
Scale factor = 7
Since the scale factor is 7, the coordinates of all the points in the rectangle Q'U'A'D' will be gotten by multiplying the x and y coordinates by the scale factor, 7
Therefore, the coordinates of the point U' will be :
U' (7x0, 7x4) = U'(0, 28)
