Answer:
Step-by-step explanation:
We know by given that the bases of the form are 10 and 18 meters, and its height is 8 meters.
The area of a trapezoid is defined as
[tex]A=\frac{(B+b)h}{2}[/tex]
Replacing given values, we have
[tex]A=\frac{(18+10)8}{2}=112 \ m^{2}[/tex]
Therefore, the right answer is D.
