ANSWER
The is 10 is meters
EXPLANATION
The area of a tra-pezoid can be calculated using the formula;
[tex]Area= \frac{1}{2} \times (sum \: of \: bases) \times height[/tex]
We substitute the values to get,
[tex]95= \frac{1}{2} \times (7 + 12) \times height[/tex]
[tex]2 \times 95= 19 \times height[/tex]
[tex] \frac{190}{19} = height[/tex]
[tex]height = 10[/tex]
The height is 10 meters.
