The diagram shows a maize plant with the following measured dimensions: leaf length = 45 cm, leaf width = 12 cm, stem height = 120 cm, stem diameter = 5 cm. Assuming leaf area can be approximated as a rectangle \( \text{leaf length} \times \text{leaf width} \) and stem surface area as the lateral area of a cylinder \( 2\pi r h \), calculate the percentage of the total plant surface area that is contributed by the leaf.
