Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2
Area of ceiling: 6 x 5 = 30 square meters:
Area of 4 walls = 107 - 30 = 77 square meters
2 walls = 6 + 6 = 12 meters long
2 walls = 5 + 5 = 10 meters long
12 + 10 = 22
77 square meters / 22 meters = 3.5 meters
The walls are 3.5 meters high.
