No need round off to the nearest tenth.
Answer:
Scale factor = 7
Step-by-step explanation:
Dilation with scale factor to map HEFG to DABC will be,
Scale factor =
=
Length of CD = Distance between two points C(0, -7) and D(-7, 0)
=
=
=
=
Length of GH = Distance between G(0, -1) and H(-1, 0)
=
=
Scale factor =
= 7
