1) Gathering the data
4 inches x 6 in
Scale 1:30
In real life?
2) Scale are by definition a proportion:
4 inches = 6. 31 x 10^-5 miles
6 inches =9.46 x 10^-5 miles
![\begin{gathered} \text{Scale}=\frac{Draw}{\operatorname{Re}al\text{ size}} \\ (1)/(30)=\frac{6.31\cdot10^(-5)\cdot4^{}\cdot10^(-5)}{R} \\ R=1.89\cdot10^{-3\text{ }}and\text{ 1.2}\cdot10^(-3) \end{gathered}]()
Scale = measure in the Draw/ Real measure
1/30 = 6. 31 x 10^-5 x 9.46 x 10^-5 /R
R= 1.89 . 10^-3 x 1.2 x 10^-3
Multiplying each dimension by 30, we'll get: 0.019 miles and 0.012 miles
So the length is 1.89 . 10^-3 miles and width is 1.2 x 10^-3 miles in real size
