Answer 2

The value of x is 42 unit.

As per given information:

Figure A represents Figure B at scale. A scale factor of 7 is used to map figure A to figure B.

Figure A has sides that are x units long, while Figure B has sides that are 12 units long.

If figure A maps to figure B with a scale factor of p, then

`(Length \:of\: side \:of\: figure\: A )/(Length\: of\: side \:of \:figure \:B)=p`

Since figure A is scale image of figure B,

`(12x)/(7) = (2)/(7)`

`x = (7)/(2) * 12`

After dividing 12 by 2 we get

x=6 x 7

After multiplying 6 and 7 we get final value of x

x = 42

The length of the side of figure A is 42 unit.
