Answer: GR = 27
Explanation:
Given: R is the midpoint of FG.
i.e. R bisects FG into two equal parts as FR and GR. [Midpoint divides a line into two equal parts.]
or we can write FR = GR
Since it is given that FR = 27
Then from (i) , GR = FR = 27
i.e. GR = 27
Hence, GR = 27 , which is the required solution.
