A) 16 cm, 4 cm, 18 cm
B) 4 cm, 6 cm, 8 cm
C) 6 cm, 9 cm, 12 cm
D) 20 cm, 21 cm, 25 cm
Correct Answer: C
Solution :
Given that, AO = 4 cm, BO = 6 cm, CO = 8 cm O is centroid (intersection point of median). Then, \[\frac{AO}{OF}=\frac{2}{1}\Rightarrow \frac{AO}{2}=OF\] \[\Rightarrow \,\] \[OF=\frac{4}{2}=2\,\,cm\] Similarly, OD = 3 cm and OE = 4 cm Now length of median AF = (AO+ OF) = (4 + 2) = 6 cm BD = (BO+OD) = (6+3) = 9 cm CE = (CO + OE) = (8 + 4) = 12 cmYou need to login to perform this action.
