| Given:
triangle ABC,
medians AM, BN and CK,
AK = 2,
BM = 3,
CN = 4.
Find the perimeter of triangle ABC -?
Solution:
Consider a triangle ABC. Since AM is the median, then BM = MC = 3 and BC = 2 * 3 = 6.
Since SC is the median, then AK = KB = 2 and AB = 2 * 2 = 4.
Since BN is the median, then AN = NC = 4 and AC = 4 * 2 = 8.
The perimeter of a triangle is the sum of the lengths of all sides of the triangle. Then P ABC = AB + BC + AC.
P ABC = 4 + 6 + 8;
P ABC = 18.
Answer: The perimeter of triangle ABC is 18.
