Ответ:
The ceiling is 3.6576 meters high
Step-by-step explanation:
To solve this problem, we will follow the steps below;
We can easily use proportion to solve this.
Let x be the height of the ceilings in meters
1 meter = 3.28084 feet
x = 12 feet
cross-multiply
3.28084 x = 12
Divide both-side of the equation by 3.28084
3.28084 x/ 3.28084 = 12/3.28084
(On the left-hand side of the equation 3.28084 at the numerator will cancel-out 3.28084 at the denominator, while on the right-hand side of the equation 12 will be divided by 3.28084)
x ≈ 3.6576 meters
Therefore the ceiling is 3.6576 meters high
