The second tree grows 2 * 4 = 8 meters in 4 days. The third tree grows 2 * 4 = 8 meters in 4 days. The fourth tree grows 3 * 4 = 12 meters in 4 days. In 4 days, all four trees grew 4 + 8 + 8 + 12 = 32 meters combined. So the final answer is 32. <hau> Itace na biyu yana girma 1 * 2 = mita 2 a rana. Itace na huɗu yana girma 2 + 1 = mita 3 a rana.
