A model of a ship is made to a scale of 1 : 200.

(i) If the length of the model is 4 m, calculate the length of the ship.

(ii) If the area of the deck of the ship is 160000 m², find the area of the deck of the model.

(iii) If the volume of the model is 200 litres, calculate the volume of the ship in cubic metres.

Figures which have exactly the same shape, but not necessarily the same …………… are said to be similar.

1. angle

2. side

3. size

4. volume

Two circles are always :

1. congruent

2. similar

3. enlarged

4. concentric

In size transformation, the given figure is called an object and the resulting figure is called its :

1. pre-image

2. image

3. post-image

4. enlarge object
