find the height of a residentail floor:

22-15 = 7 floors
76.4 -54 = 22.4 meters

22.4 / 7 = 3.2 meters ( each residential floor )

now find height of ground floor:

floor 8 - 1 = 7 floors

7 floors x 3.2 meters = 22.4 meters total

31.6 meters  - 22.4 meters = 9.2 meters
 

the ground floor = 9.2 meters
