Peak height on chromatograms

On page 74, Heinemann, Question 14 a), it asks for the peak height.
For 30ppm, the answers say it's 7.4cm. Why do I get 4.5cm? And neither of my other peak heights meet the answers.
How did you go about measuring this peak height on the chromatogram?

Thanks

When you measure peak height, you measure it from the centre of the peak. Maybe they are giving you the peak area? (just taking a guess)
