A model of a ship is made to a scale 1 : 300.

(i) The length of the model of the ship is 2 m. Calculate the length of the ship.

(ii) The area of the deck of the ship is 180000 m². Calculate the area of the deck of the model.

(iii) The volume of the model is 6.5 m³. Calculate the volume of the ship.

Triangles ABC and A'B'C' are similar to each other, the corresponding vertices of the two triangles are :

1. A and B'

2. C and A'

3. B and B'

4. C' and A

A : Two similar triangles are congruent.

B : Two congruent triangles are similar, then :

1. A is true, B is false

2. A is false, B is true

3. A is false, B is false

4. A is true, B is true

Triangles ABC and PQR are similar to each other, then :

1. $\dfrac{\text{Ar.(△ABC)}}{\text{Ar.(△PQR)}} = \dfrac{BC^2}{PQ^2}$

2. $\dfrac{AB^2}{PQ^2} = \dfrac{AC^2}{PR^2}$

3. $\dfrac{\text{Ar.(△BAC)}}{\text{Ar.(△QPR)}} \ne \dfrac{AB^2}{QP^2}$

4. $\dfrac{AC^2}{PR^2} = \dfrac{BC^2}{PQ^2}$
