Answer 1

Measure of the side, x = 5.25 units

Explanation:

Figure B is a scale image of figure A.

That means figure B is an image and figure A is a pre-image.

Scale factor for the dilation from figure A to figure B = 1.75

Scale factor =
`\frac{\text{Side of image B}}{\text{Side of pre-image A}}`

1.75 =
`(x)/(3)`

x = 1.75 × 3

x = 5.25 units

Therefore, measure of the side figure B is 5.25 units.
