Answer: Multiply the lenght and the width of the scale drawing of rectangle by [tex]\frac{8}{5}[/tex]
Step-by-step explanation:
Knowing that the scale factor used is:
[tex]scale\ factor=\frac{5}{8}[/tex]
You know that the dimensions of the scale drawing was obtained by multiplying the dimensions of the original rectangle by [tex]\frac{5}{8}[/tex].
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 [tex]\frac{8}{5}[/tex]
Then, you get:
[tex]lenght_{(original)}=(\frac{8}{5})(18\ inches)\\\\lenght_{(original)}=28.8\ inches\\\\\\width_{(original)}=(\frac{8}{5})(12\ inches)\\\\width_{(original)}=19.2\ inches[/tex]
