5. As shown in the figure, it is a black and white checkered cloth. The side length of the large white square is 14 cm, and the side length of the small white square is 6 cm. Question: What percentage of the total area is the white area of this cloth?



The side length of the large white square is 14 cm, and the side length of the small white square is 6 cm. To find the percentage of the total area that is white, we need to calculate the areas of the white and black parts and then determine the ratio of the white area to the total area.
$58 \%$
5.【Solution】The area of the checkered cloth is 9 times the area of the figure below, and the area of the white part of the checkered cloth is also 9 times the area of the white part in the figure below. The percentage of the white area in the figure below is:
$$
\frac{14 \times 14+6 \times 6}{20 \times 20}=0.58=58 \%
$$

Answer: The area of the white part in the checkered cloth is $58 \%$ of the total area.
