Answer:
A = 114 m²
Step-by-step explanation:
The formula for area of a trapezoid is
A = (1/2)(B + b)h where B is the bottom base, b is the top base, and h is the height.
We are given B = 11, b = 8, and h = 12, plug those values in and simplify
A = (1/2)(11 + 8)(12)
A = (1/2)(19)(12)
A = (19)(6) (half of 12 is 6)
A = 114 m²
