1.	1. A model of ship is made in a ratio 1 : 200.0) If length of model is 4 cm then find the length of ship.(Gi) If area of deck is 1,60,000 sq.cm. then find the area of deck of model ofship.
Answer» Ship and its model are similar figures. ∴1/200 = 4/length of ship (by the property of similarity) ⇒ Length of the ship = 800 cm. area of model/area of ship = (1/200)² ⇒area of model = 16000/40000 area of model = 0.4 m Like my answer if you find it useful!

Answer»

Ship and its model are similar figures.

∴1/200 = 4/length of ship

(by the property of similarity)

⇒ Length of the ship = 800 cm.

area of model/area of ship = (1/200)²

⇒area of model = 16000/40000

area of model = 0.4 m
