The medians AD and BE of triangle ABC meet at G. If GD = 3.5 cm, what is the length of AD?

Competition practiceGeometry
  • A10.5 cm
  • B7 cm
  • C14 cm
  • D5.25 cm

Step-by-Step Solution

The centroid divides each median in the ratio 2 : 1 from the vertex, so GD is one-third of cm.
Answer: A) 10.5 cm
