Answer 2

Answer:  Multiply the lenght and the width of the  scale drawing of rectangle by $\frac{8}{5}$

Step-by-step explanation:

Knowing that the scale factor used is:

$scale\ factor=\frac{5}{8}$

You know that the dimensions of the scale drawing was obtained by multiplying the dimensions of the original rectangle by $\frac{5}{8}$.

Therefore, the dimensions of the original rectangle can be found with this method:

Multiply the lenght and the width of the  scale drawing of rectangle by $\frac{8}{5}$

Then, you get:

$lenght_{(original)}=(\frac{8}{5})(18\ inches)\\\\lenght_{(original)}=28.8\ inches\\\\\\width_{(original)}=(\frac{8}{5})(12\ inches)\\\\width_{(original)}=19.2\ inches$
