The difference between the actual heights of the buildings is 20 metres.

Work out the height of the taller building.

Note: the height of the small building on the drawing is 4.5 cm, and the height of the tall building is 6 cm.

The height difference irl is 20m, and on paper the same difference is 15mm (1.5cm). Therefore you know that every mm on paper represents 20/15 m irl. Multiply that ratio by the taller building's on paper height in mm (60) to get the irl height.

you need to work out the scale for the model, like how many cm on paper is 1m in real life

My bad, I hadn't seen that rule. Edited now.
