Question

A model of a ship is made to a scale $1:300$.
The area of the deck ship is $180,000m^2$. Calculate the area of the deck of the model (in $m^2$).

Answer 1

$(\text{Scale factor}{)}^2=\frac{\text{area of the model}}{\text{area of the ship}}$
$=\frac{1}{90,000}=\frac{\text{area of the model}}{1,80,000}$
area of the model $=2m^2$
