Solution

The correct option is A $Scale factor = \frac{1}{210}$
Scale is a ratio, while scale factor is a value.

$1 f t = 12 i n$

$Scale = 2 i n : 35 f t$

∴ We can write:
$Scale = 2 i n : 35 f t$
$= 2 i n : 35 \times 12 i n$
$= 2 i n : 420 i n$
$= 1 i n : 210 i n$

Hence,
$Scale factor will be = \frac{1}{210}$
