G is the centroid of DABC. The medians AD and BE intersect at right angles. If the lengths of AD and BE are 9 cm and 12 cm respectively; then the length of AB (in cm) is:
Answer: (2) 10 cm
According to the question,
In the diagram-
Then, the length of AB is 10 cm.
Hence, the answer is (2) 10 cm.
please help me for math. in this question how you take
AG=6 , BG=8 , GE =4 , DG=3 what formula is used to divide total length (9 cm) of AD in two parts AG=6 , DG=3
after AG & BG length i can solve the AB length
