Correct Answer: 5 km. Given that, AB = 1 BC = ED = 5 CD = 2 FD = 9 So, EF = FD – ED EF = 9-5 EF = 4……………(1) Also, AE = AB +BE,   we know that BE = CD =2 So, AE = 1+2 = 3……………….(3) Hence, Applying pythogorous theorm in triangle AEF, we got AF 2 = AE 2 +EF 2 AF 2 = 3 2 +4 2 AF 2 = 25 AF = 5 Hence option B is correct answer.
