This tutorial will help you to calculate length of cevian in a triangle using Stewart's theorem.
Find the length of the cevian (d). Units are in centimeters (cm).
n = 5 cm m = 6 cm b = 8 cm c = 7 cm
Length of cevian (d)
a = m + n a = 6 + 5 a = 11 cm
√(b2m + c2n - amn) / a √((82 x 6) + (72 x 5) - (11 x 5 x 6)) / 11 √(384 + 245 - 330) / 11 √299 / 11 √27.18182 5.214 cm
