Figure 1 represents the export of rice by four regions in Country XX in the year 2009. One dot represents 20,000 tonnes of exported rice was used as the sca...

To determine which region exported the highest tonnes of rice using the dot map, we need to compare the number of dots in each region. Each dot on the map represents 20,000 tonnes of rice. By counting the number of dots in each region, we can calculate the total amount of rice exported by each region. From the dot map, we can see that region R has the highest number of dots, which corresponds to a total of 8 dots. This means that region R exported 8 x 20,000 = 160,000 tonnes of rice in 2009, which is the highest among all four regions. Therefore, the region that exported the highest tonnes of rice in 2009 is region R.
