Given:

Plot the image of figure ABCDEFGH after a dilation with scale factor 3. One of the side has been plotted.

Required:

Plot image after dilation of scale factor 3.

Step-by-step explanation:

A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size. The scale factor of a dilation is the factor by which each linear measure of the figure (for example, a side length) is multiplied.

We will consider distance between two points as 1 unit.

So, distance between B and C is 7 unit. After dilation by scale factor 3, length of BC become 21 unit.

Similarly,

Length of AB change from 2 unit to 6 unit.

Length of AH change from 4 unit to 12 unit.

Length of GH change from 3 unit to 9 unit.

Length of GF change to 1 unit to 3 unit.

Length of FE change from 4 unit to 12 unit.

Length of DE change from 2 unit to 6 unit.

Length of CD change from 1 unit to 3 unit.

Answer:

Hence, we can draw figure from these measurements.
