Question

The accurate scale drawing shows a car and a lamp post.

The car has a real width of 1.5 metres.
Find an estimate for the real height, in metres of the lamp post.

Answer 1

Without any measurements, it is not possible to give a numerical estimate for the real height of the lamp post in metres. However, we can use the scale of the drawing to make an estimate.

Let's assume that the scale of the drawing is 1 centimetre (cm) represents 0.5 metres (m) in real life. This means that every 1 cm in the drawing represents 0.5 m in real life.

If we measure the height of the lamp post in the drawing and find that it is approximately 15 cm, we can estimate the real height of the lamp post as follows:

Real height of lamp post = (15 cm) x (0.5 m/1 cm) = 7.5 m

Therefore, using our estimated scale of the drawing, we can estimate that the real height of the lamp post is around 7.5 metres. However, this estimate is only as accurate as the assumptions we made about the scale of the drawing.
