 ::The UN Partition plan allocated 11.4 million dunams to the Arab state and 14.92 million dunams to the Jewish state. But when the fighting ended, the land area of Israel had grown to 20.6 dunams-and increase of 5.7 dunams.

With this elementary data, the calculations seem simple enough to establish what percentage of the land allocated to the Palestinians was incorporated into the nascent state of Israel.
