The territory of the oasis is rectangular, 1400 meters long and 3/7 wide. Palm trees grow along the perimeter of the oasis every 10 meters. How many palm trees grow around the oasis, if a palm tree grows at each vertex of the rectangle.
Width = 1400 * 3/7 = 600 meters
Perimeter = (1400m + 600m) * 3 = 4000m
The number of palms around the oasis is 4000m / 10m = 400
