Since the triangle ABC, by the condition, is a preceded, then his median BM also has its height, then the triangles ABM and CBM are rectangular, and am = cm = AC / 2 = 22/2 = 11 cm.
Then in the rectangular triangle ABM on the Pythagore Theorem, we define the length of the BM category.
BM ^ 2 = AB ^ 2 – AM ^ 2 = 61 ^ 2 – 11 ^ 2 = 3721 – 121 = 360.
BM = 60 cm.
Answer: The length of the median BM is equal to 60 cm.
