Question

Michel uses the scale drawing and the scale factor to enlarge a square that has a side length of 12 in.

Which proportion could Michel use to solve the side length, x, of the enlarged square?

Answer 1

the correct answer is 3in/2m=12in/x

Answer 2

`(3)/(2) =(12)/(x)`

Explanation:

Side length of square = 12 inches.

Now we are given that Michel uses the scale drawing and the scale factor to enlarge a square

Scale Factor = 3 in. : 2 m

Now let the side of enlarged square be x

So, Using scale factor

`(3)/(2) =(12)/(x)`

`x=12 * (2)/(3)`

`x=8`

Thus the side of enlarged square is 8 m

So,
`(3)/(2) =(12)/(x)` proportion could Michel use to solve the side length, x, of the enlarged square

Hence Option D is correct.
