Question

A model of a ship is made with a scale factor of 1 : 500. Find

The deck area of the model, if the deck area of the ship is 1500000 m²  

Answer 1

Scale:- 1 : 500

1 cm represents  500 cm = `500/100 = 5 "m"`

1 cm represents 5 m

1 cm² represents 5m x  5m = 25 m² 

Deck area of the ship = 1500000 m² 

Deck area of the model = `1500000/25` cm² = 60000 cm²
