2 rectangle shaped
1) Length = 160 mi ; Width = 40 mi
2) Length = 440 mi - 160 mi ; Width = 240 mi - 70 mi
1 triangle shape
1) base = 70 mi ; height = 440 mi - 160 mi
Area Rectangle 1 = 160 mi 40 mi = 6,400 mi²
Area Rectangle 2 = 280 mi 170 mi = 47,600 mi²
Area Triangle 1 = ((440 mi - 160 mi) 70mi)/2 = (280mi 70mi)/2 = 9,800 mi²
Total Area = 6,400 mi² + 47,600 mi² + 9,800 mi² = 63,800 mi²
