The value of AG from triangle DEF is 14 cm. option A
What is AG?
As we can see in the attached figure that G is the point at which the three medians of the triangle meet, that is, the centroid
And, according to the property of the centroid, it divides the medians in ratio 2:1
So,
FG: AG = 2 : 1
Since the FG is 28 cm
28 : AG = 2: 1
28/AG = 2/1
cross product
28 × 1 = AG × 2
28 = 2AG
Divide both sides by 2
AG = 28/2
AG = 14 cm
Therefore, AG would be half of FG which equals 14 cm
