Answer:
The length of GH is 4 units
Step-by-step explanation:
We need to find length of GH
Given : - FG=2 units FI=7 units and HI=1 unit
In figure -1
FI is formed with FG , GH and HI
FI = FG + GH + HI
7 = 2 + GH + 1
7 = 3 + GH
Subtract both the sides by 3,
7 - 3 = GH
4 = GH
Therefore, the length of GH is 4 units
