Answer:
<h2>10 units</h2>
Step-by-step explanation:
It's important to know that the centroid is always two-thirds of the median. Which means

Which means
.
But, the centroid has always the same distance from each vertex, which means

Therefore, BG is 10 units long.
Here's the picture, if anyone still needs it.
Answer:
Of what?
Step-by-step explanation:
6 sides, 7 length for one side
6x7 = 42 for the first one
52 for one side, has 5 sides
52x5 = 260 for the second.
The actual amount that needs to be divided = 85
The ratio in which the amount needs to be divided = 2:3:5
Let us assume the common ratio to be = x
Then
2x + 3x + 5x = 85
10x = 85
x = 85/10
= 8.5
Then
The ratio in which the number 85 will be divided = 2 * 8.5:3 * 8.5:5 * 8.5
= 17:25.5:42.5
So from the above deduction we can see that the number 85 can be divided in the ratio 17:25.5:42.5
